Charges for cancelled line

A fault was logged with Telkom on the 3rd December 2014 - we got a lot of SMS's but the fault was never attended to. At the end of January the intermittent service stopped completely and we again logged the fault. After numerous e mails and phone calls we gave notice and cancelled our account at the end of February as the service had still not been restored. To date our account has not been reconciled and our numerous efforts to get this resolved are being ignored. We just want to get this resolved and finalised.
