Worst Customer Service Ever

<p>I have been a loyal customer of CellC for the past 10 years. This year I have received the worst service from CellC that I have ever received, I have been over charged on multiple occasions. I have had unauthorized debits for other accounts going off my account. I have been promised of credit back to my account and that a supervisor will be contacting me. This was on the 30/09/2016, up until today I have not been contacted, I have then contacted CellC on multiple occasions and have still not been assisted. I am actually disgusted at the level of customer service received considering the amount of money that we are paying for these contracts.</p>
