Telephone staff try hard but -My card was not accepted for a transaction to a company in London.Repeated attempts were unsuccessful. After waiting ages, the bank said that there was no block and that the problem was with the payee's sytem. I checked and found that the payee's sytem was fine. I tried the Bank again next day - the card was declined again. I called - waited ages again - and was told that they had blocked it but they were waiting for me to query why.I then tried to unblock - of course I waited for ages, then spoke to two contacts, then I lost the connection. I tried again, waiting for ages, and again had to talk to two contacts. I WASTED ABOUT THREE HOURS ON THURSDAY AND ANOTHER TWO HOURS ON FRIDAY, during which time the currency exchange rate fell, so I lost time and money.This is rubbish on so many levels.
