Poor Service from the biggest company, please hire on good consumer experience and good qualifications

Today the 1 September 2020, i called MTN Insurance , to request an insurance for my son 's cellphone, i was unfortunate to have ended in the hands of a lady called Dintle. According to the Policy the insurance does not cover a device that is over 30 days. I boutht the device at MTN Polokwane on the 2 July 2020, the consultant gave me a number that i should call to insure the device, i called and i was told to port the number since they only cover the on-net MSISDN, well my son has been battling to port the number, bought a couple of sim cards because it kept rejecting, until he went to the nearest MTN store to seek assistance. It was only successful on recently towards the end of August. The lady Dintle told me about the 30 days rule but i still wanted to explain to the Supervisor, she told put me on hold for some time and told me she will call me back after 2 pm to give me feedback, she escalated my query. I asked where the supervisor was and she said they were in a meeting. She failed to call me and i decided to call back. The place was noisy and i could hear consutaltants talking at the back and my call was released. I called again and my call went through to Itumeleng, i told him i wanted to talk to Dintle and he put me through, the lady said she could not call me back because she had not received any feedback, i asked her why didnt she rather called me and tell me she doesn't have any feedback as yet, i asked to talk to the supervisor and she said the supervisor left already i asked her to give me the Supervisor 's name and surname and the e-mail address she refused and wanted to give me a pool e-mail, i asked her again to give me what I'm requesting her to give me and she released the call. How sad. The entire section needs more training on professionalism and respect for customers. I am truly disappointed i must say. I bought a phone from MTN, struggled to port, when i finally get it right, this is what i get. I can never define my disappointment.
