I've tried, via the 0800 44 33 11 number to change my payment date from 22nd to 25th of the month. I want to do ths because my employer has change my salary payment date to 25th. I already have a Direct Debit set up on my bank account. I don't want to set up a new payment plan (because it costs me more money, although only 40p per month). Can anyone help me please?
