How to seperate profiles of dependents after MRV paid for both

I have two H4 dependents, I tried to schedule appointment for them by adding both of them together and paid MRV, Now i am not able to find slots as no slots available for both dependent at this time.
I want to separate them to two different ustrveldocs accounts to book appointments separately.
How do it do it.
I paid the MRV in bulk for both hence i have same receipt for both.

Call or email the VFS and they should be able to guide you.
