Worst customer services

extremely bad technical support. extremely a bad customer service. the worst part about it is that there is no other ISP in my area and I know they are aware of this. When I was unable to pay I got emails and calls wanting to disconnect me but now that there is an issue no assistance other than I must buy a new router as the 1 I have was given to me as a favor. this router has been replaced so many times with working routers same model. what has changed? The manager at IPCOMMS said he will call me back but of course no callback. I have logged calls over and over
