Repair to LG G2

I booked my LG G2 in for screen repairs on 12 December 2015. I have made numerous follow up calls to the MTN insurance department as well as the switchboard. I spoke to a supervisor and also with various call center agents. It is now going for 5 months that no one even attempted to get back to me regarding the repairs to my phone or anything. Everytime I make an inquiry as to the progress of my phone I get a different story. And I am expected to pay an excess for service like this? I have a laptop also with them but will definitely cancel all my contracts I have with MTN as this is just ridiculous...
