Terrible service from Travelstart

I placed a complaint on 4th September on hello peter, due to their lack of support for a 24x7 online booking site (both after-hour emergency timelines and urgent mailbox are non-responsive within their said SLA timeframes), I could not cancel my erroneous booking in time. They responded to my query and promised that they will sort it out. YET, over a MONTH later, the issue is still not resolved. I left at least 4 calls to Tracy who is their amendments manager, and she didn't even bother to return 1 call! Last try, I requested one consultant to place another wait list request to the returning flight. I have explained many times to Travelstart that I need to confirm my returning flights asap as I need to finalize my accommodations and other travel bookings. BUT THEY DON'T CARE AT ALL. No one is following up with airlines on my wait listing. This booking was made erroneously, I should be able to cancel within 24 hours freely, and I didn't cancel based on their promised that they will amend and sort it out for, which is total lie. Not returning emails, or calls, most terrible customer service. I will file my compliant to Travel Industry Ombudsmand, they can't run a 24x7 travel site without having a working 24x7 support desk, and processed on my credit card 20 mins after I emailed and left messages on their support line to cancel my booking.
