Dispute on Appraisal - what say you.

A drive by appraisal I had done has been disputed because  the house is a 2 bed but the comps are for 3 beds.

Appraiser said he assumed 3 bed because I didn't tell him how many bedrooms were in the house, I say he should and could have found out himself or asked me instead of assuming.

It's 30 days since the appraisal was done. 

What say you.
