Casino/bookmaker game problem advice

Hi, any advice appreciated.

Playing quite decent stakes multi-hand blackjack via a large uk high street bookmakers casino section. Played a session of about 50-60 rounds of multi-hand blackjack and had the following problems...

1. Hand where I had 6, was not given the option to hit, the system just 'skipped' over the hand.
2. Hand where I had 10 and dealer showing 5, was not given the option to hit or double, the system just 'skipped' over the hand.
3. Hand where I had soft 19 and dealer showing 7, I did not get a chance to click stand, the system just gave me another card (J) then another card (K) so bust.
4. Hand where I had 15, I chose to hit and was given a 7 so bust. The system gave me another card (5). Obviously this individual hand had already lost, it shows a clear problem with the software and with the sequence of the next card I hit and the cards the dealer took it made a big difference.

I had screenshots of the history of the first 3, and a screenshot of the game screen for the last one.

I've emailed the company and waiting for a response from the technical team.

What can I do about this? What is the likely outcome? Over these 4 hands I lost around £550 and over the session lost around £2,100. I think it is very clear there was a technical issue with the software and these were not fair bets.

Thanks
