Vision Smartlink Networking Pvt. Ltd. — horrible service

When internet shuts thay never solve problem within 2-3 days, when you call to customer care thay tells the same line that "i can update your complain and it will be solved by evening" than you call in the even for the same thay tells now your problem will resolve tomorrow. I called them every 1 hour prior thay never solve your problem quickly.
Also thay don't even adjust your plan or not gives refund.
