Disputes???

[ka2sie]

My husband and i were looking at his credit report and found alot of incorreclty reported info on both our credit reports actually. Mine only had one and I disputed and they fixed it but his has stuff like the car we let go back to the bank shows a chargeoff amount of $10k and instead of IIb its showing as charge off and several other accounts show charge off's with balances so we disputed them. Will this increase his credit score?? And when items are IIb they shouldnt be showing up with balances and charge offs right?

The Balance on all IIB accounts should have a balance of $0 from what I understand.
