EPRS Buysmart — about refund balance

Address: Pune, Maharashtra

I am distributor of eprs buysmart (Distributor no-ez03888) from last 9-10 year. I had 3180 balance in my account till day there is message of "insufficient amount balance in id". My all retailers account 's balance are also blocked, they also couldn't use their balance. After it i contacted with buysmart's sales executive there are no proper answer. And not received call. So how to release my balance.
