Gameloft — Gangstar vegas progress lost

I am an old gamer of gangster Vegas. My Gangstar Vegas I'd Gangstar24983 Today when I installed Gangstar Vegas again it is not getting my old progress data it is showing new game. Kindly check and update my old I'd. I login through Google play games. I am continuously sending mails contacting customer care but no one is bothered to reply. What kind of service you are giving worst service.
