Strongly strongly recommend everyone to never get Reliance.
I got this service in April 2012. While the first few months it worked fine (albeit much slower than they claim), since past 2 monts (starting Oct 2012), I have not had internet service.
They have raised 5 difference service tickets but failed to resolve the issues. They closed every ticket so they can meet their deadlines. But I continued to get no service.
In addition, they have only given me credit for 15 days of no service. Clearly, they do not meet any possible customer service criteria.
