Confidence petroleum India Ltd go gas - Confidence petroleum Go Gas

Go Gas company office which is located in patna told to take a dealership for Go Gas for the location of Baniyapur (Saran). Your amount is fully refundable whenever you want to exit and take Rs. ***** through NEFT in company account but due to some personal issues I couldn't take dealership. When I ask for refund they stop to taking my calls when I called them from another number, they told to send refund application when I give him than again told to send in format on stamp paper ( they mailed me sample copy of refund application) I again send him on stamp paper through indian post office. But now again they are not responding my calls. I am suffering from very critical situation. I continuously calling on these numbers ********** ********** but I couldn't get any response from them.
