Bad Service & Lack of Response

My son's phone needed to be repaired under my MTN insurance policy in December. Handed the phone in at Norwood - stating this was an insurance claim. Hear NOTHING til we queried with the store in Jan. Told I had been contacted to approve repairs - stated that NO contact had been made. 2 subsequent visits later - same story. Then told that Service is waiting for me to pay - told them again this was covered by insurance. CANNOT reach MTN insurance to activate a claim by phone. Cannot get an answer from anyone (even on Social Media - despite assurances). When I contact your repair centre I get a song promoting DAGGA usage played to me. Honesty - cannot wait til I can cancel this contract.
