Disgusting service and lies from Telkom

Absolutely pathetic service from Telkom. Been a customer for over 10 years. Recently they replaced our uncapped 4Mbps adsl line with a Wireless LTE as they advised they were doing away with adsl lines. They also told us that the service will be exactly the same and we will be paying the same. That turned out to be a big lie. With the wireless lte we are throttled for most of the day after our usage for the month exceeds 50Gb. That's absolute nonsense and never happened when we were with the adsl. Now the speeds are so slow, much less than 1mbps and impossible to use.
