Product: Credit card

To whom it may concern ; I purchased XXXX tickets from XXXX XXXX XXXX XXXX XXXX for {$1700.00} on XX/XX/XXXX XXXX ), this price was inclusive of all added fees ie. agent fees and tax. I signed the authorization form for them to take the {$1700.00} from my Chase account XXXX XXXX XXXX, however I received a bill for {$2400.00} from my credit card company ; Chase ( XXXX ). The XXXX thing I did was to contact the travel agency XXXX XXXX XXXX to see what was going on. I did n't hear anything from them so I called and they admitted that it was their fault and promised to refund me the {$680.00} that they took out extra by mistake. Unfortunately this promise was n't fulfilled so I emailed the travel agency again to cancel everything, asking them to cancel my tickets and refund me with the whole amount of {$2400.00} so that I could use a more legitimate travel agency ( XXXX ). I still did n't hear anything back from them, so I called XXXX and again they apologized and their agent- XXXX- told me she had contacted the airline XXXX to cancel my ticket but after I contacted the airline they stated that they had never received any phone call from the travel agent so I send XXXX a new email on XX/XX/XXXX ( XXXX ). That was the XXXX time I was able to speak to XXXX as they would n't answer my phone calls nor my emails. 
In XXXX occasion a XXXX agent hung up on me and ignored me, so I made a complain to XXXX ; XXXX XXXX XXXX Consumer division ) ( XXXX ), and called my credit card company Chase to dispute the {$680.00}. XXXX replied that they had forwarded my complaint to the travel agent and the airline XXXX XXXX XXXX, giving those 30 days to respond. The travel agent did n't respond at all and XXXX airline replied that the situation was XXXX 's fault and I was advised to contact them ( XXXX ). 
I received the dispute letter from Chase however for some reason it was n't for {$680.00}, they had only accepted {$590.00} ( XXXX ) and I had no idea why they had deducted {$95.00} ( XXXX ), however to put an end to this dilemma I paid the {$95.00}, although it was n't fair. 
After a few months I received a letter from Chase stating my dispute had been cancelled, and for some unknown reason I had been asked to send some documents for a re-dispute. I sent them a cover letter XXXX XXXX ) and attached all the supporting documents which would be all the appendixes I have attached so far that clearly showed that someone has conned me. Chase sent me XXXX letters on XX/XX/XXXX and XX/XX/XXXX ( XXXX ) stating that they have not accepted my dispute for a sum of {$95.00} XXXX funnily enough that I had already paid that amount ) and the XXXX! 
As it is completely clear from my supporting documents, someone is trying to take advantage of me. The XXXX thing I need to know about this fraud is whose authorization did Chase pay Fly Away {$2400.00} with? I need to know if Fly away forged my signature to take this amount or whether it was Chase who broke the law and paid them what was not authorized by me? 
It appears Chase is not taking this matter seriously and despite my best intention to resolve this matter between ourselves, Chase is not caring for my interest therefore I urge you to look into this case with utmost attention and fairly. 
I trust your judgement and look forward to hearing back from you very soon, should you require any further information please do n't hesitate to contact me. 

Yours sincerely
