No ADSL line for a month and no one can help!

We had 2 ADSL lines at Telkom. I cancelled one line effective 1 June 2015. Eversince then and even prior the second line has not been working. Logged a call with the call centre on 1 June 2015 and nothing was done. 12 June spent over an hour on a call with the call centre and no one was willing to assist as they kept putting us through to various departments. Eventually a billing agent assisted and it was not his job to do so. Only to find out that the username and password telkom provided us was incorrect and that they also changed the password for some unknown reason. After checking this the line still did not work, a technician came out and advised that there is nothing wrong with the line. Again got in touch with the call centre and they advised there is a problem with the account itself. Up until now the line has not been fixed yet we received the bill to pay our account. No one in Telkom knows how to fix this and the original people who helped us open this account (its a business account) refuse to reply to emails. The frustration speaking to someone in Telkom Call Centre where they can't even speak English or understand anything the caller is saying.Problem still not resolve
