Poor customer service. Fees for basic transactions that shouldn't cost a p in the digital era. Their bank app is very limited so for larger payments I was forced to go to the bank - something I hadn't done for years! Old fashioned.
Their staff was rude and incompetent - the cashier threat me 'I don't have to transfer your money if I don't want'. Well yes you have, the clue is in the name: it is MY money.
