Terrible first experience

Booked a flight on Thursday last week. My bank blocked it because they thought the payment was suspicious. I dealt with this almost immediately and then followed the steps on the email that was sent to me by Travelstart (When you want us to try to process the payment again on the same card please click on link) which was to follow a link that took me to a contact form (already a weird system). I did this and sent it through. On the very same email it mentions "do not rebook on the website as this will cause duplicate bookings with the airline" - so I obviously wasn't going to do that, I would wait the 24 hours to receive feedback as I've been told. That feedback never came. I have since sent about 5 mails (2 of them at 5am the next morning) and not one of them has been answered (this using the support channel and the "live chat"). I then called on Tuesday, spoke to a women and then got forwarded to a man who said they would look into reinstating the ticket as is, he would send it back to the lady I had just spoken to and that she would be in touch. Its now 48 hours later and still heard nothing from her. Phoned again, spoke to someone who was actually willing to try and help. She agreed that the communication issue has been disgusting and that the guy I spoke to on Tuesday should have helped me there and then. But still she can't do anything for me and it looks like I'll have to spend a lot more money for a similar ticket. The issue with my bank is on my side but surely this happens often? I did everything asked of me from that point on and I have received no support from this company - your poorly built systems and almost non existent support team should not be my problem.
