Very Poor Signal on new LTE line vs. old ADSL

Last year we had a 10 mb/s ADSL uncapped line installed at our house. All was well, installation was quick and painless. Then months later, Telkom contacted us to advise that they are contacting all ADSL customers to switch to Home LTE which offers the same line speed and other benefits. I asked if we can refuse the migration to stay on the ADSL, which was working very well, with download speeds of up to 9 mb/s at peak times. To this question we were advised that if we agreed to stay on the ADSL line, Telkom will just not offer support on the line in future if a fault was to arise. We agreed to do the migration. Then we heard nothing.

Weeks later, we contacted Telkom to follow-up when nobody could advise as to the status of our request. We again concluded the order. Again NOTHING came from it. Out of the blue, in 2020, we receive an SMS on Monday, 9 March 2020, that our order has been handed over to the courier and that we should receive it soon. Promptly the courier arrived with the new LTE modem and SIM.

Once installed, the SIM took about a day to be activated, all is fine, BUT THE LINE SPEED IS TERRIBLE!!!!! THE BEST WE HAVE HAD ON THE LTE, WAS 6MB/S DOWNLOAD.

We have tried moving the router around in the house to no avail! This is the worst internet you can get - Telkom Home LTE.

When we log a fault on the Telkom App, nothing comes from it!

What kind of service delivery is this?
