Pathetic Service!!!

I have a contract with MTN for almost a year now.On the 5th of June I got ****** with my phone, I called the call centre to block my SIM Card and Phone but they were on strike,I had to go in store to block my phone and SIM Card...How inconvenient. I then sent through my claims form after waiting almost 2 weeks for a ITC Blacklisting number, I then called the call centre to follow up on my claims form I was told that I will be called by Friday and I am still waiting. I tried calling today over 5 times on the *** number and before I get through to a consultant the call cuts. The lack of communication from MTN is really infuriating and I am honestly LOATHED by their service.
