Terrible Service

Tried to call to change a debit order date as my salary date as changed. I got told I must pay double the amount to do so when I said I can't afford to do that I got told well that's my problem and they can change it but it will take off double the amount and they not promising a reversal. Next issue I have TWO loans I have paid off have gone twice to the branch for them to close the account and get the paid-up letters. I understand due to trying times that the banks are understaffed and its a struggle however I have not even seen the inside once and now get told that if I don't close it before the debit order date they will deduct that from me too. Somethings got to give!
