LBF Travel Inc. Withdrew money from my account for an airline ticket I NEVER bought from them. San Diego California

Last year, I purchased a round trip ticket from Tucson to England directly from American Airlines. I then received several voicemail messages from the "help desk" of LBF Travel Inc. letting me know that my itinerary had been changed and that the trip would cost more. This company was unknown to me and I eventually learned that I had two one way tickets to England and no ticket to return. They also withdrew money from my bank account on two occasions even though I never solicided any services from them. Eventually I was able to obtain my return ticket from American Airlines/British Airways, since I had originally paid for it,  to come back to Tucson. However, I still have not yet been reimbursed for the funds that LBF Travel unknowingly took from my bank account. I have made multiple attempts to get back my money from them without success. I am getting the run around.
