MuchBetter Contactless Payment Device - fob

I bought this for my father, who has dementia, it was impossible to set up the muchebtter account, they make it so difficult. I transferred £50 to muchbetter and they could not trace it and then wanted my father bank statements! to show the money had been transferred, I am not prepared to send the bank statements with all of my fathers information on, so we lost the £50 and the cost of the fob! Ridiculous and an unrewarding experience......
