Terrible service from Telkom

I have been trying for more than 2 months to get my landline number that I have had for more than 40 years to be activated/reactivated. I have been to the Chatsworth offices more than 4 times and was advised the number is no longer active on the sim, the number has been moved to a line since I have a fiber line. I was advise 3 weeks ago that a technician will configure/calibrate my landline. This has not happened, I went back to the store and was advised to buy a new phone as the sim is active. This is not the case, the sim has been disconnected and is no longer active. I went back to the store yesterday after calling 10210 and 10213 and receiving no assistance from Zinhle who advised to request for a technician to calibrate the line. I received no assistance at the store and was told they were offline. This has been on going since the beginning if July.
