Inconvenience to life, messing with my credit record

<p>I recently upgraded my contact and since my upgrade my account is over charged every month. The first time is happened I was told by a lady called Theodore from Cell C social media team that the company accepts the fault and it will rectify it. It happened again and now I can pay my other accounts cause Cell C feels like all my money is for them. All they know is to apologize for the inconvenience but never fix the problem. The first time I waited over 3 weeks for my refund after being told that it will take 24 -48 hrs, I am currently waiting for my refund from this mess 2nd time around and it's been over 2 weeks now. </p> <p>They even forcefully want to offset my account with the over charged amount for the following month after I explicitly asked them to refund the money back to my bank account. It is really frustrating when my other accounts go into errears because Cell C prefers over charging me every month. </p>
