Pathetic customer service

Pathetic customer services.. Their accs dept is pathetic. They were debiting my acc on a Saturday if payment date fell over the weekend for 3yrs. This year they decided not to do debit orders on Saturdays and change without notification. When questioned they statw that the contract stipulates working day debit orders yet for 3yrs.. they were debiting on weekends. They changed to suit their convenience and evade the issue at hand. Notify clients so that they can make prior arrangements. Not change to suit yourself and your convenience. Plus they are quick to double debit an acc and place clients in financial situations. Pathetic service in their accs dept..
