Pathetic Service

I changed my bank and have emailed all the proof 4 times as well as called 3 times, Still unable to change my debit order for my vehicle to be deducted via debit order. This is annoying as this was a simple request end of March already and now have to keep tranfering money through to different bank account to pay it manually via eft as i do not have the time to go and deposit this in at a bank....
