I've had my share of problems with playing Slotomania, but, mostly it is due Flash Player which is being phased out. I have never had a bad experience with customer service, in fact, quite the opposite.
They are pleasant and helpful. Transcripts of all chats are sent via email for follow up. There was one situation where I could not send nor receive coins. They actually set up an appointment for a tech to call me on a certain day.
The tech called, as promised, and logged onto my computer remotely as I watched every move he made. He changed some settings and gave me advice on how to keep things up and running. It was great.
I agree, it is not fun losing coins, but, I've also had great wins. (Just like in a real casino.) So, to those who are upset with the company, there are other games out there to play.
