Poor service/ Breach of contract/still no ADSL/

I have lost access to my ADSL for over a month due to Telkom's errors. First they suspended my line because I did not pay an amount I was disputing. They came back and said this would be reversed as it was an error on their part, yet they continue to charge me even though I did not have access to their service?? I asked that they open my ADSL line, they assured me that this would take 7 days. I called after 7 days and they told me that my line is still suspended yet I keep getting billed? How can I keep getting billed if because of their mistake I am not getting any service. All I keep getting is being passed from one call centre department, why must the customer have to fix their error?<br> <br> I was also told that they have a new offering, a 10mbps line. I signed up and paid for a few months, now that I moved to MWEB, MWEB tells me I am still on the 4mbs line?? This sounds like ***** at the worst and questionable business practice at the very least!!
