Alliance — No internet service

There is no internet service since the past two days. The user id is renug_sl. I have called the local internet office but they have been looking into it since forever now. This happens very frequently. Once they tried to even sell me a new router saying that there's something wrong with the one that I have and it had barely been a year since I got it, and all this was for complaining about the the connection issue. Luckily I didn't fall for that made up stuff because my router was working fine. I renewed my data pack about a week ago and now I can't use the services for the past two days.Kindly look into this.
