Disgusting service

On the 20th of January I called Telekom to install fibre in my home, I gave the agent all the necessary details, but to my surprise I was told that the fibre was already installed which was not. I called telkom and was told that the agent chose a wrong address which is my neighbour and I was advised to log a new call and they would cancel the first call. A month letter I started receiving emails (billing) of R3000 and some odds and one for R315 (which was the actual fibre charge I opted for) When I looked at the address on the invoice it wasn't mine but my neighbour's, I again called telkom to rectify it on the 3rd of March I received a text saying its resolved( to my understanding they have removed my husband's name on our neighbour's invoice) so last week I called telkom for a cellphone, today I get a call saying I'm declined because I'm unfit customer who doesn't pay!!!! I have bought many products from telkom and have trusted telkom but now I'm shown flames. Right now I have a cellphone contract(36m) with them together with the fibre but because the mess that one agent made on my husband's account this is how we are treated. Everytime we call the call centre we are always told that they will resolve like this is from January it's March but nothing is done. I'm appalled!!!!!
