Airtel Digital TV — Non installation after a week of payment

Address:

Thiruvananthapuram, Kerala

I on behalf of my friend made an online payment to Airtel Digital TV through Vritiinfocom (billdesk) with their reference no 3914241 on 09/09/2011 for a DTH connection at Trivandrum. The payment was claimed by Vritiinfocom on the same day from ICICI Bank vide ID no 456182. But till date (15/09/2011) customer id is not created, nobody in Airtel Digital TV has any explanation, all what they say is "with in 2 hours you will get a phone call" which never happens. I am making three to four calls a days wasting my time and energy.
I am still in dreams about the connection.
Can anyone suggest a way out? How to fix these rogues?
Can any one share the experience?
