Hathway / Gujarat Telelink [GTPL] — wifi not working since 3 days

First of all very poor service from gtpl. I mean pathetic. I will not renew it after its expiry for sure. I had called many times to customer care since past 2 days that my wifi is not working still none of their technician had visited to my premises. They only say that sir your request is under process. Technician might be coming from u. S. A i guess. Poor very poor service. -5 stars to this so called gtpl service.
