Truly Professional - Raising the Dead

Reviewed on 2021-05-07T15:29:54

My Late partner passed away in 2009 having suffered a truly MASSIVE STROKE. Whilst appreciating thatlarge and multinational companies feel they are above the laws of man this organisation goes one better believing itself to be above the laws of GOD and Nature. This morning despite 12 years ago having registered my partners name on the Bereavement Register to avoid receiving painful letters and e-mails I received a post card addressed to him; clearly they believe they can resurrect the dead !!! ( something I believe only Jesus Christ could do). I spoke with customer services who at first found my comments amusing, actually Laughing before changing their tone and being promised - Leave this with me and I will see what I can do.... I have asked that they raise a cheque in favour of Guy's Hospital Rheumatology department to the tune of £1,000 to compensate me for their lack of professionalism in processing mail to my late partner so close to the anniversary of his death and his Birthday. Today I discovered that they made s paltry donation of £250 hardly compatible to the pain they inflicted on me so close to the anniversary of his death and his birthday... But then perhaps to this organisation GAY LIVES HAVE NO VALUE !!!
