Purchased a washing machine and tumble dryer from this company . Both black Beko products .The washing machine stopped emptying out the water properly after 2 years and the tumble often smells of burning and takes 1-2 hours to dry basic cotton sheets . Absolute rubbish

Insurance claim

Reviewed on 2021-03-29T12:19:32

I insure several commercial properties with the insurance broker part of this company.I recently tried to make a claim, which they disallowed. They didn't try very hard to fight my case with the insurer. I had the feeling that they are overloaded with clients wanting to make claims and I just wasn't a high priority for them.

They lied to me!!!

Reviewed on 2021-03-20T13:47:50

They told me that I would get reimbursed for my psychological treatments, and then one day out of theblue they sent me an email saying they wouldn't. I opened up to them and said that I have received psych treatment in the past but for a different reason, and they said that what I said is classified as a different reason and I can just start the treatment and they'll pay for it (on-call). But, then I got an email saying my problems are pre-existing and I am not allowed to get a reimbursement, and at that point, I am almost at the end of my treatment. I admit that I sent the review late but they said it was okay, and they'll still review it and reimburse me for the treatment that I have done.

Reviewed on 2021-02-07T00:04:57

I Never/Rarely get my monthly disbursement in a timely manner. I no longer deal with the children in YSA as it is always a frustrating situation and I have never settled an issue without escalating,which is also great if you want to get totally pissed off. I now deal with someone at a higher level and have better service... Hate this deal between Mercedes and these bozos...must have been deal made on the golf course?

Incompetent

Reviewed on 2021-02-05T11:19:28

This company keeps sending letters to my deceased father asking him to outdate his details,despite being told of his death and despite the fact they are now paying the spouses pension to my mother. Judging by their responses they don't read letters and when asked to send updated pension forecasts they send ones nearly a year old. Incompetent in the extreme.

I wish it were possible to give 0 stars

Reviewed on 2020-12-28T16:55:52

I wish it were possible to give 0 stars. Not only did the delay in receiving this health insurance lead to being unable to visit a doctor upon moving to the country,causing me to almost become hospitalised and continue to suffer health problems over a year later, but they really try and suck every cent from you for terrible coverage. I missed a payment one month and instead of alerting me, the emails went to an account I did not have access to because they didn't set my account correctly. I did not notice the fine grow until bayliff type letters came through. I set up a payment plan and paid the full amount, almost six times the original size and am still being charged "administration" costs despite not being a customer for over a year. Again, the total is going up despite proof that I do not need to pay this. Nothing about this insurance was good, I've had nothing but stress, pain, sickness, misery and fines from AON and truthfully they will take as much money as they can from you. Run away.

Failing Pensioners Continually

Reviewed on 2020-12-14T14:13:13

These lot administer the various defunct Smurfit Kappa UK defined benefit pension plans. When you retire,do NOT expect to draw your pension anytime soon after. In fact, you could be waiting up to a year, as some have found out if AVC'S are included. I'm currently 6 months in after retiring early. Consistently being let down by their slow and somewhat incompetent approach in dealing with the member's pensions. They blame Smurfit's free employee advisors and vise versa. My correspondence, I've found went unread or not read properly. No-one seems to want to take responsibility for what is someone's much needed income. I am now in debt and trying to survive doing part-time work, at minimum wage. Smurfit Kappa UK pension trustees and management are equally to blame in allowing this company to administer the schemes. Something desperately needs to change here, but I truly don't hold much hope for my Smurfit colleagues when taking retirement. 7 months it finally took to get an income and a further 3 for AVC'S to get sorted (again chasing). After unsatisfactory complaints handling, I'm left no option but to contact the ombudsman.
