Monthly Query escalation still remains unresolved

<p>looks like I'm going to raise this query every month . Once again Cell C debited my account with the incorrect amount R378 instead of R199. I have been raising the same query since August 2016 and the issue continues to re-occur. I posted on their facebook page on the 1st Dec and they still have not responded to my query after informing me they are investigating. This is bull**** I want to cancel the contract.</p>
