moving from postpaid to prepaid

I went to the store, and after waiting for an hour, the agent said my previous account owner would have deunify the account.

This seems to be the real problem. Are you the account owner? Or is your line on someone else's AT&T account?

The only way to switch from AT&T post to pre, or visa versa, is in an AT&T store.  

If you are not the account owner, you need account number and pin code to switch

Unified billing is a whole other mess.  The account owner does have to de unify the account to manage wireless.  

Ridiculous, but wireless can’t be managed while unified.   

Thanks! I had a particularly bad experience at the ATT store in Mountain view, CA. The bottom line is the customer service agent over the phone kept saying I would have to visit the store for some permissions that they didn't have, and the store agents kept saying I would have to call customer care because they lacked some other permissions. This went back and forth thrice - so far I've spent 6 hours on the phone and 4 hours at the store, and I still haven't switched to prepaid.

I'm under someone else's account. My issue is that I've had to ask the owner to call 3 times so far, each time for something different.

Since ATT can’t figure out how to do it, an alternative is to port your number to another carrier’s prepaid. I don’t believe the account will need to be de unified to allow a number to be ported to another carrier. If you still want to use ATT prepaid, wait a month and port it back.

@sumeetwisc Has the account owner completed a transfer of billing responsibility to authorize your taking over the line? If not, that can't be done over the phone. Account owner needs to go here: https://www.att.com/tobr

If that's been done, and you have a unified account, there isn't an easy way to get through until the account's been separated.

@QuarryRye The OP wants to move the line to prepaid. A TOBR is to transfer the line to another postpaid account.
