What happenedDescribe what happened so we can understand the issue ... 

Dear Sir/Madam, We are XXXX XXXX and XXXX XXXX XXXX. 
XXXX XXXX charged our XXXX XXXX credit card XXXX amounts of {$1400.00}, altogether was {$2800.00} without our consent. The story was : On XXXX XXXX, 2015, We used our XXXX XXXX credit card booked and paid for XXXX round trip tickets from XXXX to XXXX for {$1000.00} each through XXXX. 
The round trip ticket shows, we fly with XXXX from XXXX to XXXX and fly back by XXXX XXXX. 
On XXXX/XXXX/2015, We boarded and flied with XXXX was fine. The return trip on XXXX/XXXX/2015 with XXXX XXXX which check-in and boarding was smoothly, they DID NOT said any thing wrong with our tickets. until we checked our XXXX credit card statement. We found out XXXX UNAUTHORIZED charges of of {$1400.00} each, altogether is {$2800.00} by aircanada.com on the date we flew back from XXXX to XXXX on XXXX/XXXX/2015. These return trips were included in our PAID round-trip tickets. Why they charged us again for the trip we already paid for. 
First We called XXXX XXXX to complain about XXXX unauthorized charges, they said we need to contact XXXX XXXX to solve these problems, which We did. 
After weeks of complain with XXXX XXXX, on XXXX XXXX, 2015, they only credited us XXXX of {$530.00} ( Refunded XXXX money of round trip ticket? ). We think the XXXX credits of {$530.00} were NOT the right amounts which XXXX unauthorized XXXX charge of {$1400.00} each, still {$1800.00} short. 
On XXXX XXXX, 2015, We sent registered mail to XXXX XXXX to complaint about their credits to us were NOT right amounts, but they replied " Was unable to obtain credit to our account ''. These were really unfair practice of Bank of America to their customers. PLEASE help us to get back our hard working and saving money back. 
Thanks for your reading time and helps. 
Sincerely. 
XXXX XXXX and XXXX XXXX XXXX is my " RESPOND '' : XXXX said " I engaged directly with Air-Canada to purchase the ticket ''. On XXXX, 2015, I only CHECK-IN with my paid tickets, NO PURCHASE new tickets at the counter PERIOD. 
Can XXXX shows me the credit card receipt with my SIGNATURE agreeing pay for the tickets on XXXX/XXXX/2015. ThanksXXXX XXXX
