Useless customer service and online payments fail

I bought a Cash Passport for my trip to UK. Upon arrival I tried to use it to activate my SIM card it didn't work and I didn't think much of it. It wasn't until later when I tried to buy Christmas presents on Amazon and couldn't check out that I realised the problem: online payments weren't working. I made numerous calls to CashPassport and Amazon and everyone was blaming each other. I think I made over 6 phone calls to CashPassport. I was told 3 times that they would email \platform"and phone back when they get a response -- I waited for a week in between calling and still haven't received a reply 5 weeks later. 1 of the people that worked with me even claimed that there was no record of transactions from Amazon a few times only to tell me about 10min later \""oh here they are\"". That same person also told me that they would email me once they emailed platform because she wasn't able to cc me in the email to them -- I'm still waiting for that email too.. My last phone call to them had the lady offer to send me a new card -- which arrived 4days later and surprise surprise no difference!<br> I also tried adding both cards to PayPal which failed too<br> I am very disappointed with this service """
