Ongoing fault for 3 months

The saga continues now 3 months down the line and we are still sitting with the issue of slow and a dropping line at least 10 times a day. Had a technician here today who was more interested in going on holiday than wanting to help and did nothing to check if he could find the fault. I am beyond frustrated and annoyed, doesn't matter how many call center agents or supervisors I talk to a different story is given every time, and there is never a call back to update me where we are in getting this resolved. If there was a rating score below zero that's what I would give telkom. So I am still sitting with this issue unresolved is there anyone at telkom who is willing to help me get this sorted out before I have to start looking for alternative internet solutions.
