Reliance Money — processing fee not refunded

I ask for a four lac loan... They ask me to submit kyc documents... Then they ask for a 5500 processing to be deposited in their account... I deposited the same in 10 mins... Then again msg came from their side... Your loan is approved but your amount is on hold... Now you need to pay rs 15999 as a security fees...
Now i decide to cancel my loan application
And tell them the same... They said ok ur processing fee will be refunded in 2-3 days.. After 2-3 days they are bot responding to my msgs
