Worst Telkom Customer Service at Mall of Africa

Today I just received a shock of my life from Telkom and the same branch in Mall of Africa which I have been using their services for the past 3 years. I wanted to book in my phone so that they can fix the screen because I had insurance but I was told my phone does not have insurance and the person who who helped me does not work here anymore so they can not help me wow......

I bought a Huawei P20 on contract 2018, 2019 I took a SIM contract for data because I thought their services are good. towards end of 2019 I lost my P20 then I went back basically to upgrade my contract I ended up taking 2 phones plus insurance. Now 1 year 5 months down the line am told " You don't have insurance and we can't help you because the person who helped you doesn't work here anymore".

Worst service ever and I cant wait for the contract to END so that I can change providers. Please recommend provider with better reception because it looks like I have been loyal for nothing.
