MTN is a ***** up, should be penalised in SA

I took two new contract phones with MTN and unfortunately one was ****** in my room. I called MTN to blacklist the phone, gave them the IMEI number, but they said they cant pick it up, I will need to go to the store, with an affidavit from the police station. I did that, went back to the store and they sent an email to bulk blacklisting. To this day, MTN has not black listed the phone. I know this because I had my tech friend checking on it and its used by a cell c number. The phone was not insured and I am not going to pay for it until you come with proof that you have black listed it. If you want to suspend my line, go ahead, will simple buy a phone and use a different network, you ruin my credit record, go ahead, but I am not going to pay for this ****** phone until you give evidence of its blacklisting. You do a debit order, I will reverse it. You need to treat customers fairly, you will get in SA what you got in Nigeria. If I have to mobilize people, Il do that.
