Travel Agents

There is an Agency with two names. They are expert at cheating passengers EXACTLY like M&K Travels...There is a guy named ABHINAV MADAN. He is one BIG Fraud. I bought NW flights tickets for $ X amount STL-BDQ...and then I had a date change due to family reasons. He did re-book it without ANY extra charge...told me that he booked in the way that was good for me....BUT...HERE GOES THAT CHEAT...he charged my credit card 2nd time for that return ticket amount and told that he will return that money he charged for 1st time booked tickets. I had to go through pains of contacting Northwest Airlines with all booking numbers..travelling dates and Citi Cards too. Citi cards was very helpful in getting my money back after almost 1 yr.!!!!
