HDFC Bank — Home Top up loan

Hi, I have recevied the call from HDFC and they have told you have eligible for home top up loan with lower interest. So i have applied the top loan through online, they have assigned one exectuive name is Vignesh [protected]. He don't have time to think, everything is ok, just need to pay process fee. Then i have paid process fee 5300 .
After i paid the fee, next day everyone came for address visit and office visit .2nd day onward i am only follow with executive . After one week he credit score not match with your requirment and this amount is non refundable.

My purpose of post, if any one looking for home loan or top loan, please check twice before pay the fees.

Worst experience with HDFC.
