No service

My Black berry started to get warm. I took it in for repairs in July 2014. I've received the phone back 6 weeks later just to find out that it doesn't read the sim card. Ever since then i am trying to get my phone back. The technician working on the phone is MJ and his contact details is ***. I've paid for the phone to be repaired and got it back with an different problem. I can't keep on following up with Hendri and can't see why I must phone the technician.
