Inexplicable Terrible service from Telkom

App**** for the transfer of a landline (including data) from one address to another in the same residential area (March 2018). Followed it up on numerous occasions with ZERO result or feedback from Telkomto date (13 June 2018). How is this possible and why can't Telkom fix this elementary situation in ten (10) weeks time??? The service is absolutely appalling if not Non-existing... Can someone with the necessary authority PLEASE sort this matter out without further dekay and advise me accordingly?!
