Account deduction and terrible network

I've been experiencing problems with this network for a very long time.

I'll start off with the fact that I've instructed them to call 3 of my contract with them. I've called the call centre several times with an instruction to do so. Their East Rand Mall branch have contacted me several times asking if i want to renew my contract, of which i said no every single time. The contracts came to an end in Aug 1, Sept 17 and April 17. I've realised that my bank account has still been deducted for the past 3 months for these contracts. One of the contracts was put on a month to month basis which i also cancelled later on but my account is still being deducted. I have not been using any of the minutes or data i usually get because i was told it will stop when the contract comes to an end. So why am i paying for something i havent received. What i find ironic is that when i called to cancel and was put through to the retention department, cell c all of a sudden wanted to give me a better option hence the month to month. Ive called in Feb 17, May 17 and Aug 17 to cancel my contracts but clearly the *********** staff on the other end did not follow the instruction. I've just finished a call with Nfundo in the retention department ref ********** ********** which indicated that they will listen to my calls. I highly doubt anything will happen. So i want to know will Cell C reimburse me for the monies deducted when I gave you an instruction to cancel my contract.

On top of that I've always experienced terrible network and I've called in several times and it keeps getting escalated but i never hear anything from anyone. I fill in forms and nothing happens. I've contacted Cell C via FB and get told some ridiculous story about a roaming agreement with vodacom when asked how do i do that i receive no response what so ever. Its very rare if someone gets hold of my because my phone goes directly to voicemail and only receive an sms an hour later of a missed call. Every single time that i call i get some flimsy excuse i should remove the sim, switch the phone of, use another phone. How about taking some accountability. And dont come and tell me about that you will send a tech out I've been hearing your stories for to long.

Is this the manner is which Cell C treats their customers?
