BLACKLISTING OF MY PHONE A COMPLETE NIGHTMARE

My phone was ****** on the 8th of November, i must say getting my phone blacklisted has been a total nightmare. 1st i called in to blacklist my phone i was told that the model of the phone is wrong therefore they cannot assist, i was referred to the store,which i went to, only to be told that the system is not working. I was sent back home without getting any help. I called the call centre where i spoke to some guy named Luvuyo or something like that (a supervisor) and i was told to go back to the store, he refused that i scan the receipt and take a picture of the box and email it to him. First of all its not my problem that you have the wrong model of phone and why should i bare the costs of driving not once but twice to your shop to get my phone blacklisted. I am really annoyed and really not considering using your network again. I have been a loyal MTN customer all my life but after this pathetic service im really done with your network.
