Disgusting service from MTN

I am disgusted at Mtn and their customer service. For 2 weeks now I have been trying to get my VODACOM phone number unblacklisted from them. They have incorrectly blacklisted my phone! I bought my phone sealed at a store and have not had any other SIM card besides my own in the phone. I have been dealing with mtn back and fourth as they want to blame Vodacom (and vice versa) when on the system it shows "blacklisted by mtn"

Doesn't seem like I will get my phone unblacklisted even though I have done everything and provided everything they have asked for to start the process. Promises of the phone working within 72 hours has been nothing but lies.

They also refuse to provide me with a managers contact number to sort this problem out. Next stop laying a charge against mtn.
