Telkom woes

So here's my experience with Telkom. I have been without service for seven months now. Towards the latter stages of 2018, i began experiencing problems with the lines in our area. So we were without service for a few months. Eventually, in December, Telkom provided us with a wifi cordless phone so that we won't have to rely on the physical lines. The new phone only worked for about 2-3 weeks before it refused to power up. I phoned the Telkom call centre and they advised me to take the phone to a Telkom store for repairs which i did. It seems that the company that delivers the phones actually provided me with wrong phone in the first place. This was picked up when checking against the model and serial numbers. Now Telkom is refusing to take this phone in for repairs as it was not the phone assigned to me. This isn't even my fault. I have been multiple times to the store for assistance and it seems that no operator or manager can assist me. I just get the run around. In the meantime i have been paying for non-existent services. Can somebody please assist me? This is very frustrating.
