VODACOM!!! I am Disgusted in your customer service

My husband took out a contract with VODACOM, on the contract I clearly stated a debit to go off at the end of every month, Firstly they took it off before the 27th which was a Thursday so it bounced then when his salary did go through they took R396 his contract states R279 a month I call the VODACOM customer service following up what is going on she tells me that it bounced so they charge him R100 penalty fine. What the Hell !!!! They take my husbands money when they shouldn't be touching it yet and then still fine him for there Mistake I am furious. !!! How Dare Vodacom. I strongly want people to Know what ****** we are dealing with and I WANT my husbands money back in his account or so help me I Will take this Further. Best Someone get back to me and not have your service providers putting the phone down in my ear !!!
