Uniconnect — wrong sim given and no refund is being made

i was leaving for a tour of scandinavian countries. At T3 airport in Delhi, i went to buy a prepaid sim from their counter inside the airport. Salesman took a copy of my boarding pass and passport and gave me a sim with phone number wriiten on it.On reaching at my destination, i realised the sim was not working. After lots of mail interaction i was told that 1. the number written on sim card cover is not complete. 2. Sim given to me is not valid for scandinavia . I have been mistakenly given a sim for usa. I requested them to refund my 2000 rupees upon arriving back in india. Inspite of several calls and mails, uniconnect is not responding at all. It is an absolute case of cheating as well as deficiency of service. First, they gave me wrong sim because of which i had to waste lots of time and money, secondly they are not even refunding my money. vinita gupta [protected]@yahoo.com
