So after 10 days of waiting.. I finally picked up my lower.. and when I paid for it 10 days ago.. the gentlemen that rang me up scanned it and it was lower than it was marked for.. I asked again before giving him my plastic card.. The total was almost $200 dollars compare to $310 (cost of the complete lower) When I signed the paperwork 10 days ago, the paper stated it was paid in full and all sales are final.. come today, I went it and the gentlemen was like.. it was rang up wrong.. I was like.. okay.. how much do i owe you? he said $180.. so now my total is close to $400 compare to the $200 I paid 10 days ago.. If I screwed up on my part, I would be completely fine with it.. my question is, is it my fault that it was rang lower than it is marked for? am I the one accountable for it? if not, can I go back and talk to the store manager about? cause is an $200 dollars difference from what I paid for 10 days ago.. thanks guys..
