Extremely bad service

Went to the garage, already put in petrol and tried to pay, card declined saying insufficient funds, logged into the app and there was more than enough funds for the transaction, I even transferred more money to the account to make sure, still could not tap, swipe or draw money, spent an hour and a half on the phone, for them to tell me it’s an IT issue and that my card was fine but there’s nothing they can do, I was stuck at the garage for 2 hours until my girlfriend could get there to pay for the petrol! This is unacceptable service for a bank!
