Your Source bank is HDFC or Kotak?And what about the HDFC Pno, is it linked with SBI unipay?
I don't know based on what he has suggested it, he can only answer that. Or may be because of copied post. If SBI has processed refund and given refund reference number and even then it's not credited then only it makes sense to contact source bank, in my view.
Though, try contacting kotak also and see if they can check.
