Cancels my 1 line & now 2nd line also not working

I get back to work on 4 January only to find my 1 line is not working. This was a pre paid line that was working on a PABX system. When i call telkom to see whats wrong - they say they have cancelled my line because the yearly fee wasn't paid. No call, no SMS, and no Email stating anything of the sort was sent to me. Telkom *******ly cancelled my line. I have had to order a 'new' line to be installed. I was told it would be done last week. Then i got an sms that it would be done Monday 18 Jan, no one came. Then i got an SMS that it would be done Tuesday 19 Jan. no one came. When i call to ask whats happening - they say it will get done. Today when i asked, i get told it will get done only on the 26th Jan - This is almost a WHOLE month i have been without this business line. Then, last week my 2nd BUSINESS line stopped working. I have been phoning everyday to get this sorted, my business has NO INCOMING TELKOM LINES. WE ARE LOSING A LOT OF MONEY! No one can help me, no one can give me a manager or technicians number, no one can escalate this problem. This is an utter joke! Fix my lines TODAY Telkom!
