Bad service and no "installation"

App**** for 20mbps line and the sales consultant checked and said everything is ok. I baught a new router from them. We had to wait 14 working days for the new line to be installed by their service provider, 14 days came and gone, I know the Covid19 has everything in a complicated spot. My line was activated. I had to re route my line thru the old D-link router because the land line is a Rj11 cable and the new router uses a ethernet Rj45 cable NO ISNTALLATION DONE!!!, We had to downgrade from 20mbps to 10mpbs line because the line does not support 20mpbs. Now we have been struggeling holding the line for more than 40min at a time, I even had to send pictures to them, all they need to do is give me a splitter box for the cable or a compatable line, problem solved, I have explained, send pictures and explained more to what the actual problem is I was told to go buy the splitter box, but should the line or box not be part of the instalation hence the 14day waiting period for line isntallpation that was not done. There was only one consultant that really helped me she tried her best, routing thru the old router but it did not last. But overall BAD SERVICE!!, Looks like I will have to fix this my self.
