Error which linking old bank reference number to newly migrated ustraveldocs website

After ustraveldocs.com got migrated to usvisascheduling.com when I tried to link the old bank reference number to the application on the new website it gave me an error: “Could not find a Receipt with given Receipt Number and Payment Date.”

Previously it gave me the error code: “RCE07” but now I keep getting “Could not find a Receipt with given Receipt Number and Payment Date.”

I am not getting any response from customer support.
Does anyone know any solution to this?
