Pathetic And Useless Service

I booked a flight on Sunday and Travelstart did not debit my account properly then tell me that if the payment is not before 23:59 i could loose my booking. I spend 2 hours on the phone and no one answers. i spend another 2 hours on Monday and finally get someone who tells me i can EFT the remaining amount which i then do. Then i get a message saying thank you for proof of payment but the amount may have changed because of the time difference. So i must pay the difference because you can't process the payment correctly??? Now i go online to my profile and the trip is cancelled???? Cancelled after you have my money and again i am on the phone waiting for someone to never answer??? What the hell type of company is this?
