Cell C - Non existent Customer Service

Somebody *****ulently upgraded a contract that was under my name. They tell me it was done over the phone. I ask for the call log, still need to investigate, still no feedback. They say the phone was delivered 4 days after I reported that there was a *****ulent upgrade done on my account, ask them what address it was delivered to, still need to investigate, no feedback. 2 weeks have went by with no resolution. I had nothing to do with this but I was required to complete an affidavit at the police station and send through to the ***** department to prove that I did not do the upgrade or have the phone. Utterly pathetic service. Phone them for feedback and hear that the affidavit that was completed and sent a week back was not even attached to the case. Does anybody actually work at Cell C? Is there any policies and procedures that need to be followed or does everybody do whatever they feel like? This needs to be resolved and you need to take accountability for the situation. If you have all these checks and procedures in place when doing an upgrade, how was this upgrade even done without me? The first I come to know about this upgrade being done was a debicheck mandate coming to my banking app that I rejected.
