Double Charged and No assistance

i am a regular user of eBucks travel and it has usually being a pleasant experience. I booked a flight on the 8th of March and the payment was reserved and I received a confirmation indicating my flight had been booked. I then received a call the next day from eBucks Travel stating the flight was not confirmed. I explained to the agent that the funds are still reserved. He stated he would called the bank and ask them to release it and I should then book the flight again. The funds were released however a week later there were two settlement of the flight on my account from the Merchant. Further, my account balance is maintained at a certain level in order to ensure I don't pay an account fee/bank charges. However, due to the double debiting I will now be charged an account fee. I have called numerous times to dispute the transaction and have been provided with incorrect forms.
