Phone cut, irrespective of query in progress

Hi, l did not have service from Telkom for more than a month, starting the 15th of January 2016. The service was restored last Monday. I logged a query with regard to the bill of over R800 due to the fact that my line was dead for more than a month. They have not come back to me with an adjusted bill, the query is still open, but they cut my service and are refusing to assist me and restore the service. The line in question is ***, l will happily pay if they ammendment my bill to reflect actual usage, l will not pay for a service l didn't have.
