Duped out of balance by an involuntary bet change

I experienced many technical issues whilst playing on this site in the past, such as being thrown out of games constantly, which I complained about, but the strangest thing happened to me since. I was playing 64 Gold coins Hold and Win on 15 September at an initial bet of R3.50 and later moved to R4.50, playing the latter bet amount consistently. Then, all of the sudden, the strangest thing happened. I pressed start as usual, thinking that I am playing my usual R4.50 bet and then all of the sudden, I get a message saying insufficient funds which shocked me, as I had +/- R5900 balance. When I looked, I saw my bet was changed to a ridiculous amount of R2700 which is the max bet. This shocked me because at no point have I selected the plus/increase button, enabling me to change the bet and select such a ridiculous amount, nor was there a max bet button that I could have pressed accidently for my bet to have changed from R4.50 to R2700. I knew the burden of proof was going to lay with me, as the customer service would say that I did this voluntarily, I looked at the set up of this game, i.e, placing bet amounts etc and after looking at my history and the time lapse between the R4.50 and the R2700 bet, I saw that there was a 9 second time difference and that there was no way that I could have even changed the bet in that short time, when it takes me 2 seconds on average between each spin to press the start button. And I know for a fact I did not change the bet and emailed customer service with screenshots of my history for this game and also informed that if you look at my entire history of playing on this site, they will see a trend and that I will never and have never staked such a big amount. I have never betted over R100 ever and even a R50 to R100 would be rare for me to do. I initially contacted the chat and they said I did this voluntarily and they have no control over my bets....then I emailed customer service, on the 15th September and even cited that the site generally have technical glitches which I have complained about before and after many follow ups, still till today no outcome was given, only automated responses of "our technical team is investigating".

This experience is so disturbing and I have a distrust now with playing on this site, because my balance was just taken under the guise of a changed bet to a maximum amount, which was not voluntarily done, but seemingly hard to proove. However, taking into account the technical glitches experienced for which there is a paper trail on HWbets side, my history and the type of player I am and the time lapses between the bet change, it does not look that unlikely that this could have just been a technical glitch. But no assistance is being provided by HWbets which is frustrating and very dismissive. How does this betting site want to retain customers but do not want to assist with pertinent queries or issues. This experience just makes me feel like I was duped out my balance
