D-VoiS - Broadband Pvt. Ltd — No internet connectivity. Need Refund

Address: Mumbai City, Maharashtra

I had renewed my internet account with D-Vois ion and successfully paid the amount via online payment. However I didnt recieve any internet connection to my line. After raising multiple complaints I was told every time that the engineer would come and resolve the issue but nobody reapired my internet connection. I had to take another connection from another ISP and had to pay for their connection which is working fine now. I need the amount refund from D-Vois ion internet cause they took the money but never gave any internet connection despite many compaints raised.
