Not resolving problem and bad customer service

Been with Mweb for many years. Had 4Mbps line but never got those speeds, in many cases as low as 0.37Mbps in most cases. Technical department were not able to resolve problem. Call center advised me to upgrade to 10Mbps line which I did. I never get anything close to that speed, best being about 5Mbps but once gain, in many cases much slower speeds than that. Technical subsequently advises me that I can only get 6Mbps in my area. So, Mweb advised me to go for 10Mbps line and subsequently advise me that it is not possible. Mweb also sent Telkom to come and have a look at line and during this process they disconnect my voice line! Product team investigates possibility of offering alternative package in the circumstances. Response from Ryan, after several enquirers from my side, final answer is that they are not prepared to do anything. Paying fro 10Mbps line, getting halve of that if I am lucky. Asked Ryan several time for escalation procedure, no response. Answer is final. Bad service and extremely disappointing.
