Rummy Grand — Fraud app as cheating and looting

I deposited amount and played games like all apps but here I win some games and lost some games and I tried to make withdrawal up to withdrawal nothing as same as all rummy apps, now after withdrawal they blocked and saying irregular and abnormal so blocked I didn’t understand that I asked what is this they even don’t have no reply other than this.. in my account I have 74000 so they intentionally want to loot money so blocked my account it was very clear and they don’t have contact number don’t have office address and don’t have any mail I’d all are fake which was mentioned
