Very bad service

Since travel start double charged me for my flight tickets on the 4th of January, up until today i am still waiting for money to be released back to me. The ticketing agents keep giving me inconsistent information. Two told me money will be reversed back into my account within 3 days, that was on the 7th of January, after a whole lot of back and fourth calls and emails to travelstart. As of this morning after i inquired as to why the money is not yet in my account, i was told by another agent that i need to get an authorization number from the Bank, no one has ever told me this before last week in their emails or calls. I called the bank, the bank says no Travelstart need to give them an authorization number from their merchants, i really dont know what to do anymore to have this frustrating situation dealt with as a matter of urgency. i am just drained and waiting for the day my money will be paid back then never again will i use this company in my life.
