mtn mistakenly blacklisted my contract phone.

My name is Lungelwa I have an MTN contract phone which was blacklisted without my concerned and I have never lost or reported my phone ******. This was in 19 May 2015 when my phone got blacklisted and because of strike I couldn't get assisted. Documents were sent to the MTN branch in Jabulani mall, Sandton city and emailed to one of the team leader at the contact centre (un-blacklisting forms, affidavit and copy of my ID) until now they haven't un-blacklisted my phone and I pay my contract every month. It has been 3 months without a phone. Can't I get another phone while they are busy trying to figure out how to un-blacklist my phone. This is ridiculous all I need is to use my phone that i pay for. Or are they going to reduce the 24months contract to 21months contract because I haven't used my phone for the past 3 months and its nit my fault. What's going too happened to the data bundles that expire every month which is not fair.
