"Payment Errors? or a ****?"

After booking my flight late in the evening (10:25pm) and completing payment, I was sent an email notification to say the payment was incomplete. This was required by 23:30 the same day or my ticket would be cancelled. The link attached to the email refers to SEVERAL banks as way of payment and I was double debited. After contacting them and being on hold for over a hour, the client assistant indicated that I was to check on my side if I had been refunded and this would take up to 24hrs. Within 48hrs, they sent the entire amount back and indicated that I had forfieted my ticket and my booking refernce was invalid. Again after being on hold with them, I was sent a new payment link and indicated that (out of the goodness of their hearts) that my booking was being held for me but I had to ensure to complete payment by 13:00 that day or my ticket would possibly increase again. Never book with Travelstart! It seems like a ****.
