Unnecessarily putting you in arrears!

Vodacom is the worst!!!! I regret to have taken contract with them. I have called in January when switching banks and I have requested they change my debit date and they have been debiting okay, till now that my contract is ending they changed it without my concern. Now, I need to keep the funds I owe them till the 4th of May whereas I have requested they debit every last day of the month!I am so ****ed!….
