Spidigo — Not providing services and refused to refund

Address:	382424
Website:	www.spidigo.com

I purchased spidigo broadband plan 4 Mbps unlimited for 18 months for Rs. 12, 500.
I gave them 12, 500 rs check on 25-may-2017. As they promise they were going to install broadband connection on Saturday 27-may-2017.
But they didn't.
After calling 15 to 16 times they finally they came on 28-may-2017 at 4pm and done half installation.
Since we installed the broadband connection we complains about low speed and irregular connectivity.
We visited their office and asked them to discontinue their services since they are not providing well.
They refuse to listen a single word. Since the day we are facing bad internet speed. We have complain almost 4 to 5 times in a week. Still they are not giving a good services and refused for refund and not showing any terms and condition. We ask them to give answers in written but they also refused to do that.
Please help us out here. Our register username at spidigo is mahesh64.
