Worst service ever. Payment gone out on C Card not recognised. Telephone lines dreadful, every other word cutting out so after seven calls and one hour+ on phone, can’t clear security as can’t hear each other properly - so now they’ve locked me and themselves out of my account. Will have to wait for a security code to come in the post! Given post these days that’s about 10 days. Asked repeatedly to escalate it to a complaint and the ‘agent’ just blocked the request every time. There’s not a separate number or email for complaints or to report suspected fraud - just the general number with really obstructive call handlers. As soon as this is sorted there’s a pair of scissors going to the card. Steer well clear.
