Telkom fibre

I recently ordered the Uncapped FTTH Promo (Openserve Fibre) R399 fibre line. On the 20-05-2021 the technician came to do the installation, however; he said that the optical network terminal has a red light which is an indication that the line is not live, as a result, he said he would report back to the office and request that a specialist be dispatched to fix the line; he further said he would come back with the WIFI router and complete the installation the following day. it has been 10 days and there has not been anyone dispatched or any communication from Telkom or Openserve. I have written countless emails, called the technician on his personal number, and even went to the Telkom shop but still unable to get help as they keep on telling me that the "installation will be completed tomorrow". this is really frustrating as I have already canceled my subscription with my previous internet provider and will be left with no internet for work
