Misinformation and terrible service

I am immensely frustrated and irritated right now. I phoned Telkom on Friday night past repeatedly, holding for ages and having the calls cut out repeatedly before actually having someone answer. In the end I was told BY TECHNICAL SUPPORT that I could only be assisted with my technical issue the next morning. I called the next morning, tech support synchronized my line speed closer to the 4Mbps line that I initially requested. I was then put through to Sales (as I was advised) in order to increase my line speed to 8Mbps. I was told that it would be completed within 24 hours and provided with a reference number. The next afternoon, I called and was told that it was still in progress and it would take 48 working hours. Last night I called in because my internet keeps dropping now. I was told to call Sales this morning as the faster line is not indicated. This morning I chatted to an agent online and was told that it would take 7 to 21 days. I am already paying my ISP for a 6Mbps line and Telkom is wasting my time. Please escalate this. I would like this process sped up as I was misinformed by YOUR agents.
