Telkom's Worst Customer Service

I took an upgrade at Telkom on the 14th of December, iPhone 6S for my brother. I took it back on the 4th of February. The phone could not charge and the scream was freezing. Telkom said it will go for repairs but I will not get a loan phone. My brother was without a phone for 2 weeks. I got the phone back on 19th of February and had to return it back to Telkom. We could not switch it on and it would still not charge. It came back with a scratched screen because it was wrapped with paper and an elastic in a plastic bag. I asked for a new phone because Telkom sold me a faulty/ damaged phone. They told me the phone has to go for repairs 3 times for me to get a new phone. Telkom asked for Find My IPhone to be deactivate the second time the phone went for repairs. This means the first time they didn't even try to fix. I still have not received the phone. I paid full monthly instalment for February for a phone I do not have. Telkom has the worst customer service, terms and conditions that only serve them. Telkom terms and conditions do not align with consumer rights. How can they expect a brand new Apple iPhone to go for repairs within 2 months of purchase. It evident that I was sold a faulty/damaged phone by Telkom. I really feel cheated by Telkom.
