Bad service from MTN

I got a contract phone for my son at MTN and got insurance on the phone. Screen cracked, went to fill in a claim form for screen to be replaced. Waited more then two weeks to hear from MTN insurance if my claim is approved. Went to MTN again, after difficulty trying to find out why I still didn't get feedback yet, I was told that the copy of my I.D that was send from MTN, wasn't clear. But they never in that more than two week contacted me to tell me that. So MTN faxed the copy again to the insurance. Than I waited another two weeks, foned the insurance again to hear if my claim is approved or not. They said they still waiting for who knows what. Another week and a half went past phoned the insurance again. The guy said they send me a email. Turn out they send it to a wrong email address, gave him my email address. Got the email wish said that they gonna send me a email after 24 hours adout my claim...waited again a few days phone again. Phoned again to say I'm still waiting for the email to say if my claimed was approved. Eventually I got the email to say my claimed was approved. Payed the access the next day, the phone was picked up by the courier company on the following day on the 13th of February 2020. Till today I am stil waiting for my son's phone. It's almost three weeks now...phoned them again today. Just to hear they still waiting for some code or something. I MEAN REALLY NOW, MONEY FOR MY BILL IS BEING DEDUCTED FROM MY ACCOUNT BY DEBIT ORDER EACH MONTH ON TIME, BUT I MUST STRUGGLE TWO MONTHS JUST TO GET A SCREEN TO BE REPLACED??? MTN SERVICES IS THE WOST, NEVER GONNA DO BUSINESS WITH THEM AGAIN. CONTRACT IS ENDING THIS YEAR, THEY BETTER NOT PHONE ME AGAIN TO RENEW MY CONTRACT!!!!
