Telkom not responding to Queries

We have a LTE Connection via Telkom, however this connection is quite poor so we were advised by one of the Telkom agents to get an external antenna. We got the external antenna but we need one of the Telkom agents to come out and get it pointed in the right direction to pick up the best signal. We have tried but we don't know where exactly the towers sit. We have requested an agent to come out on numerous times as well as asking them to just call us to speak to us over the phone. This has been ongoing since last year and Telkom never come back to us! Telkom, if you do not respond to this query and sort out my issue, I can assure you that at the first available opportunity I will be moving my account!
