Sir in case of recovery suit the limitation period is of three years to acknowledge the debt. Since you have exceeded the limitation period you can give a legal notice for returning your money if he doesn't respond then along with recovery suit you have to file a con donation of delay application and explain to court as why there was a delay.
if court accepts your application and condone delay than only your recovery proceeding can start.
Also you can file a cheating case against him under 420 IPC
