SBI Epay is the payment gateway for sbi unipay.. on the screen with INB ref num, you get SBI epay on top..
The transaction ref might not match in complaint form, i had to use 'others' category to raise complaint.
They've closed the complaint asking for sbi epay ref num or merchant order num..
The correct amount transaction isn't shown in SBI Unipay and the success screen only had INB ref num which i already provided along with hdfc's UTR.
Not sure where to get the Ref Num they need.
I'll write back again and see if this can be sorted..
So far I've not received refund. 6 days have passed.
