Travelocity — Credit card charged 8 times

I tried booking 2 round trip tickets from Newark, New Jersey, USA to New Delhi India. My credit card was charged 8 times for the same transaction. The total charge I saw on my credit card was for $23,000 and each time I was told that the transaction did not go through. I was not issued even a single ticket and we were on the phone for 4 hrs. 1st with travelocity to make the reservation and then with credit card co. and travelocity, travelocity customer service, billing department. Why should we have to go through all this mental torture? We thought booking online should be easy.
