Incorrect Billing Amount

<p>I upgraded my contract on the 28th of Dec 2016 via my nearest branch. In Feb 2016 I notice that I didn't receive my package bundle as I had aggreed and signed for in the store. I contacted the lady whom was responsible for my contract and said that my contract never went through and se will sumbit it again. On the 20th of March 2017 I received a sms to congratulate that my contract has been PROVISIONED to My MTN Choice +S as I wanted and signed to. At that stage I was extremely unhappy as this took MTN nearly 2 months to do. All went well until on the 17th of March, I receive the most disgusting staement EVER! I was backdated for some *********** idiots whom doesn't know how to do his job in the first place and now I have to pay the price for this person. Why should I be punished for this as this is a problem on MTN's side and not on my side. I will not pay backdated billing on anything whatsoever!!! Please fix my contract and make sure my contract billing on my 1 phone is updated and 100% correct. As they did with my sister aswell in Nov 2016. If not fixed I will be forced to put in a stop order at my nearest bank and will never use MTN again. I have 3 contracts with MTN and this is utterly poor service by far! PLEASE FUX ASAP BEFORE DEBIT ORDER, IF NOT WILL PROCEED WITH STOP ORDER AND CONSUMER PROTECTION ACT....</p> <p> </p> <p>Regards</p> <p>****ed off Client</p>
