No telephone or ADSL data since December, 2017

I have reported a fault over ten times on my Telkom telephone and ADSL data line, since December, 2017. The reference number is 517CRK131217. Nothing has been done about it ! I don't have an operating telephone or ADSL internet. I have still been sent accounts every month and I have just paid over R600 this month for a service that DOES NOT WORK. Please get back to me and get this fixed. Terrible service from Telkom. I require a credit for two months of no usage!
