INCOMPETENCE!!!!!!!!

We had an ADSL and the contract lapsed and we were advised by Telkom to go LTE, we took their advice. Firstly they brought the router without the sim card, then brought the sim card without activating it. The connection took forever. Finally we ourselves got the LTE up and running and few weeks later the landline started acting up. Now we cannot call or receive calls and this has been going on for like a month now, business productivity is slow. I did complain on Twitter but they are also ***********. I do not even want to start with the call centre absolutely USELESS.
