Gamdom is indeed no control with ut because the slot provider is the one who set's it. You should redirect your concern on slot provider support instead to gamdom since you have problem with there software limit.
The center here is the deposit here but the casino contributor is here so there should be a paid casino if there is any problem with the provider from here then the casino here should be relaxed from here but the users here have the casino of the service provider a service offer and There is nothing wrong with many failing here but there is no need to pay due to the mistake of the provider
I am not full aware of case since Gamdom team didn't make any comment but all I know it is possible to change ba backend settings on user end. Casino accepts bet or refuses to pay is next step on such cases, btw such interventions have been happened and again I don't accuse anyone changing slot settings. Just my personal opinion.
