Mweb Stonewalling

I have had a problem with cancelling an Mweb account when I was moving, as they did not advise what I should do or what I could expect. They had a hold on my Telkom line number so Telkom could not cancel and I then incurred costs from Telkom! It is impossible to resolve an issue with Mweb as they make you jump through hoops to have a continuous conversation. After each conversation you start from the beginning again with a new person. Mweb have acknowledged some guilt but it is impossible to move forwards because they stonewall/make it difficult to reach them/don't have a direct number to phone for complaints. I have posted before on Hellopeter on this matter and they actually responded with incorrect information, implying that they weren't at fault. They admitted afterwards by phone that the information wasn't correct. I wonder what will happen this time.
