Bad service

MTN insurance is giving me the baddest treatment one can get. I claimed a phone 8 weeks ago and they gave me a phone that had a defect. I called them after 3 days of receiving the phone (which took 3 weeks) that the phone is freezing, it took them more than 2 weeks to take the phone. They now have taken the phone for repairs. A phone I only had for 3 days. They are now refusing to give me a new phone It's been 8 weeks & counting. I will never recommend MTN insurance to any one. Called in more than a 100 times and their call center agents either drop the phone, mute and give u no reference number Had I known I would have never used their insurance. Still haven't received my phone in over a month
