I am in desperate need of a new phone and my contract is up so I went into the mall asked about their plans and what the cost of the phone on the plan was he told me it was $330 for the phone with the $80 plan he wrote it down for me and I told him that I was going to look around at some other store and their plans 

In the end it was the $330 that sold me so I went back there and told him that I would take the phone so we start doing all of the stuff to get on a new plan and starts doing the paperwork then he goes oh the phone price is actually going to be $430 not $330 that I originally told you sorry 

I asked him if he could lower the price because he did in fact tell me the other price even wrote the price down for me  he said no 

I told him to cancel the whole thing and I wasn’t going to get the plan or the phone 

He looked so mad and said really that’s rude don’t be like that 

I said sorry 

Am I an asshole for walking out of the sale
