PayUMoney — Account put on Hold and not responding to queries

We used payu money as a payment gateway for our website. We received our first order of 12600 rs but payu money put our account on hold and not responding to ticket raised properly. they are just giving same answers again and again and not providing any solution. we have given all the required documents but still they are just passing time. no customer care number is available and only robot chat everytime.
our merchant id is 8672902
