Telkom Lte - data goes missing

Beware!!! I went onto Telkom Lte with Mweb (Total joke, beware of Mweb as well, I have done a separate review to deal with that).

Warning... the system does not work correctly, data is being ******. I have notified Mweb on 2 occasions. This last time, I lost 20G. It happens when you top up data. This "once off" data gets used until your recurring monthly data comes in. Whatever data you had not yet used on the once off purchase, gets frozen until the expiry date, and then disappears. Instead of finishing the "once off", the system immediately starts using your new monthly recurring data allocation. Mweb refuse to even acknowledge the issue and duck and dive every query or complaint. I have proof. Not that complicated. I have been told that I have to wait for another year, before I can leave Mweb/Telkom Lte, without being penalised.

In addittion to having lost chunks of data, the line is shocking!!! The worst. I cannot work from home, and have had to get an alternative wifi product. Telkom Lte gives me about 2mbs download speed and next to nothing upload speed. Technical people from Mweb have told me that the advertised speed is not guaranteed and suggested that I pay the Telkom "exit fee" and go over to MTN Lte, as this works. ?
