I bought a voucher online and I am charged £5 for handling fee and plus interests on that for the next 2 statements, even though I pay my balance in full by direct debit. I rang and explained this. I requested to remove it and they said they cannot. I explained that I am not aware that it was being charged as a cash transaction and that the other bank card did not charge me any cash handling fee for the same transaction, they should at least inform and let the customer make a known decision! Another credit card does not charge for it and creation does for the same thing, on top they charge you interest on it for 2 months! Rediculous!
