Blacklisted IPhone

Vodacom blacklisted my iPhone since October 2017. The IPhone was bought from MTN, I don’t know why Vodacom blacklisted it. I found out that it was blacklisted because I took it to an Istore as soon as it stopped working. I’ve been inconvenienced in a huge way, I ended up buying a new phone, spending money they I wasn’t even supposed to use. I submitted all documents Vodacom needed to unblock it, but upto today, the phone is still not working. I have made a lot of trips to Vodacom to check the progress of this issue. I would like to be compensated for all the heartache and inconvenience Vodacom caused me.
