Harrassment

I applied for the new internet connection with the company on dated protected/protected/protected. The representative named Gulshan Kumar took the installation charges i.e. RS protected. But I haven't got the connection till date. I called the customer service many times to give me the update or to refund the paid amount, but I did not get any positive response from them. It has been around 4 months I have not received the connection or the refund. I also have customer agreement form ( Sr.No. protected). Everytime when I call them, they provide me different contact number to call, they are harrassing me. I am extremely frustrated with the customer service. kindly look into this matter and provide the resolution. I solicit your cooperation. Regards Mandeep Singh Minhas protected
