Very poor service from Telkom

I am very dissapointed that it's been 9months Telkom failing to remove my name on default. They **** to me. On the 8th of August 2018 saying they have sent the request to all relevant credit bureaux to remove the adverse handover status and default history. I have just confirmed with Transunion that there are no documents which were sent by Telkom. I have tries ti call Charmaine Dafel from Telkom credit management by this number ********** 345 has been busy. I would like to know why Telkom is failing ti send the document.
