Betvictor Casino -Not able to provide adequate assistance and proper investigation on a reported slot game glitch

I opened bet victor casino to play Congo bongo while on the main board of the bonus round 8 times multiplier and most characters collect the amount I had won was around 4300. All the time I was playin the game I was getting a message sayin there was a problem with my internet connection and I kept needing to reload the game. Finally wen on a sub section of the main bonus the game froze with that message again but this time is stuck at this point and still is till now on my account. After contacting there help service I did the usually deleting history cache I tried different devices and even someone else s internet connection all the same thing. BetVictor asked for speedtest which I sent 100 mb as this is another thing they tried to blame. I sent them screen shots of the issue as well which is still clear to see on my account. They says to me then they sent to the developers. So every week for about a month I was emailing askin progress. They had been saying to me ok we can see the developers are actually getting somewhere with this we’ll email you wen it is resolved. After around a month they finally got back to me there resolve was have I tried to reload th game to which I obviously wasn’t to happy about after the emails I sent with wat I had done and screen shots and everything. After a few emails back and forward they then says it’s my internet connection. Bearing in mind I’ve been playin slots on there site all,through this issue with no problems apart from this game and am still playin on the site with no issues. The game is still,stuck at the same point on my account after telling BetVictor am not happy with there responce to this I have heard nothing at all back no offer of anything to help or come to a resolve which is why I have come to you guys now. I have the screen shots I sent them and the emails back and forth from them if they are needed. I just feel like after a month of them tellin me the developers were gettin somewhere to then ask have I tried reloading as a resolve to the issue was an insult. So I hope you can help
