MTN BAD Service with their useless Insurance

I have been without my phone for a month, ever since it went for repairs with MTN insurance. MTN referred me to their insurance so that I can deal with them even though I don't have any contract with the insurer but I have a contract with MTN. The insurer said I must deal with the suppliers and I refused. Every time I call the insurer Amanda Vester she gives me attitude telling me that she is waiting for feedback since Dec 2018 from the suppliers she promised me a loan phone she never delivered and not even bothered to give me an update on either. I am so sick and tired of MTN after being with them for more than 15 years and paid for so many contracts.
