PATHETIC SERVICE & AFTERSALES SERVICE FROM VODACOM

I changed my FTTH from a business account to a personal account and once cut-off, it could not be reconnected. I had to wait for 4 weeks for a technician to come & install a new NOKIA router. This installation took place on 10th May 2019. Since then and after numerous service requests & daily calls, the problem does not get solved!! Initial Service request number prior to changing the router was SR190 ********** 57. After installation the following service request SR190 ********** 21. WHY can this issue not be sorted & who can I contact to resolve this issue?? All i get told by consultants when i call ********** is that it "will be escalated"
