Telkom Mobile - Old cancelled contract still showing active with amounts owing. Disgusted.

My credit report shows my old telkom mobile acc is still active and with an amount owing.

Going through past old emails, Telkom even confirmed that my account was cancelled, 3 years ago! This obviously has been negatively impacting my credit record and wish I knew about it sooner.

They don't provide a contact number to the billing department to get this resolved.

Really poor as even back then I battled to get the contract cancelled with multiple reference numbers noted.
