Unlimited LTE - poor reception, no FREE antenna received

We've installed unlimited LTE +- December 2016. We are entitled on a FREE antenna to improve reception on the router. During February 2018 a very helpful employee at the Festival mall Telkom shop, Jabu, listed a request to "review" the reception at our home in van Riebeeck park. Up to today, 15 March 2018, we have had no feedback regarding the "investigation" and no antenna was set up. Not to mention that the technician only pitch about 2 hours after the agreed time. I had to leave for work and could not receive any feedback in person I had to arrange with our domestic to allow him access to our home. Telkom gave me a call to find out if we are happy with the outcome of the "investigation and subsequence implementation of the suggested advice. . On which I told her there was no action taken The lady, Lefentsi, said she will revert the call back to the technical department. On this we are still awaiting either feedback or another visit from a Telkom technical employee
