Reliance Communications — indoor network problem

Address:

Nagpur, Maharashtra, 440009

We have wireless phone in which we have inserted reliance sim ([protected]). For first 1 month everything was going well but suddenly after that there was no network in the phone. We took the phone outdoor on second floor then it was catching network. We have taken this number for commercial use and displayed it on hoardings for customers but now it has become useless for us. We have done compaint from where we took the sim he tried few things like changing the sim with new sim but nothing worked. He told that the signals of the towers are weak and nothing can be done.
Its my humble request to you to please look into the matter and atleast inform us that is the issue resolveable or not?
