Unhappy customer

Worst service ever....

On the 9th of May I went to Newcastle Mall branch and was assisted by a lovely lady, she assisted me with the Covid-19 relieve for 3 months.She phoned the head office and arranged for the 3 month relieve period. I was given two ref numbers as there are two accounts. At the end of May still the one amount was still deducted. I then had to contact the helpline at my own expense just to wait 20 minutes to be told but there was only arrangement made on one of the accounts.Why would someone make only one arrangement if you have two accounts..the money was paod back into my account just to be takrn out AGAIN two days later. I then haf to phone them again for it to be corrected (pathetic). At the end of June I phoned again to make sure all was in order and was assured it was. Now at the end of July it has been deducted again. I havr emailed them as everytime costs me money for something I am not at fault at. The problem.is with them
