Telkom fibre installation --- pathetic customer service

The nature of the email is to lodge a complaint about the terrible and pathetic service we have been receiving from Telkom. My dad and I confirm an order for fibre installation at our home on the 25th of April. We were told installation will take 7 to 14 working days. As of today the installation has not been done and we have not received any feedback from the Telkom(sales consultant, call centre, technician) regarding the delayed. We have contact the call centre on numerous occasions and always been told the same thing , that a technician will contact us. The sale consultant Zolile Nkomo is nonexistence. I will like to lodge a formal complaint against him as well. My dad and I have contacted him on numerous times for feedback regarding the order but we have not received any feedback from him. To me it seem as if he has got his sale and commission and doesn’t care to follow up about his customer. I can’t believe how bad his customer service level are. No feedback or follow up. I hope we get this matter resolve soon.
