MTN no communication

Telkom gave me someone else's number when i app**** for a new phone line which of course i had no idea about. I then app**** for a bundle 2Mb/s (line and data) from mweb on the 25th of Feb. I waited till the 10th of March for my data to be activated. Once my DSL was synced i waited another 10 days for mweb to unlock my account as it was suspended and no one could tell me what was going on. After many emails and calls back and forth i eventually threaten to cancel and get told i need to phone during office hours for that, which i didn't cause i work during the day. I then get a call from mweb saying they found the problem. they thought i was the previous owner of the line number and i had to authenticate myself to them. he then apologized told me the month would be free and asked if i would reconsider my stance. I now find out the data cancellation has been possessed and the line given back to telkom as well as being charged the full amount. when i queried this with billing i got told that they charge from activation date not on data usage.. what? Who is talking data usage? They do not call back or talk to each other and when they do they over promise and under deliver. Not happy
