Unacceptable Customer Service

It's been more than two months that I've been experiencing degraded internet service. The issue experienced is related to a slow synch speed. On numerous instances I've logged calls and when someone eventually looked into the call the agent would reset the port, and the synch speed issue would be resolved for about 3 to 4 days. Thereafter the synch speed would drop. Lately, I've also been experiencing issues with voice, were the internet is still functioning with slow response and the voice is either dead or very noisy. In the last few days I've been contacting the call centre more regularly and none of the agents are able to assist or even escalate the issue when requested to do so (147CRK220216). Based on past experience, I'm sure at some point the logged call will be closed as resolved, even thou the problem would not be resolved. I recommend that Telkom starts to review efficiencies and capabilities of their call centre. This is really unacceptable and pathetic customer service.
