Excitel Broadband Private Limited - Disconnectivity and soo many unresolved tickets

This is Prashant, I have been facing the issue with disconnectivity for a long time now. In just *-* days I face the same issue. in just ** days I faced the issue for like * times and faced the disconnectivity for around * days. Today I got to know that they have incorrect information on their databases. Status of connectivity is showing active at their end but the internet is still not working. Every time I ask for the resolution they just tell me that the same will not happen again but the issue is still here. I got frustrated now and when I asked to terminate and for the refund, they just refused to provide the same. I paid for the services and they are not providing any. I have * unresolved tickets for more than * months now. And no one is working to resolve them. Also, I raised the ticket for the new router since the router is not working properly as well but that ticket is still open and no one is working on them. When I ask regarding the updates, They got in shock that these many issues are unresolved. I have all the proof for the same and no one is even thinking to resolve the issues. And when I ask to transfer the call to the upper management, they refuse to transfer the call and the issue left unresolved. Even the local vendor is not supportive and argues to us every time when we ask for help. I also asked them to provide the static IP for * months back, Everything got finalized, they even provided me the test static IP and was working fine and after discussing the Extra charges and the documentation, I have still not received the static IP and the ticket is still open for * months now. The main issue is of disconnectivity which I am facing for a long time, The network is not reliable. There is no time when I can say the net is continuous for more than * days. No one even bothers to resolve the issue once and for all.
