Hathway / Gujarat Telelink [GTPL] — Refund for a feasible connection

Address:

GTPL House Opp. Armieda, Off Pakwan Cross Roads,Sindhu Bhavan Road, Bodakdev, Ahmedabad - 380059

My name is Anshuman Pathak and I am from Varanasi Uttar Pradesh. Pincode 221002.
As this is work from home time, I also thought to get a ISP connection. There are not plenty of options available in my city. So I thought to go with GTPL, as it was offering decent plan for decent price.
On 13th of September, I contacted local guy who is a sale staff of gtpl ISP connection. I paid him 6000rs and he did my registration and he told that it'll take around 12-13days to setup connection at my place. I paid him, and I got email and sms on mobile from [protected]@gtpl.net in which there was recipet of my payment. After 2 days I got my user ID through SMS.
Now cut to after 13 days, when I called him he was not answering my calls, after 3-4 tries, he answered and said that he will come tomorrow for wiring then he never came.
Then I contacted gtpl and after several emails and tweets, they said that connection at my place is feasible, that it can't be done.and they said to apply for refund. And for refund I had to email them which I did.
From that day till today I contacted gtpl via twitter email and through call. All they say to wait for 24hrs but they don't do anything. It's been more than 1 months. Now they ignore my emails.
