Poor service for over 1 month

Good day

I have logged countless faults with the latest reference number: 390CN ********** and reference number: ********** with regard to a faulty handset/ switchboard supp**** by Telkom. It is unacceptable that I am getting such poor service. I have had a technician come through and fix it already in the first month of getting the handset but this only lasted for 3 days. There doesnt seem to be anyone who wants to help which is pathetic. Surely someone can come assist as this is now affecting the day to day business which pays the Telkom bill at the end of the day. This behaviour is extremely unprofessional.
