Internet Connectivity issue

Please note that reliance broadband has power backup issue as soon as the power goes the internet is also gone and when power is back it takes 2 hours minimum to start. The problem is power backup at their server end, they send a service manager at my place this shows that they don’t want to understand the real problems.
The same complaint has been registered so many number of times however they are not listening the same every time they just send a mail stating that my problem has been resolved this time I have decided not to pay the bill till the time the same problem is resolved
