<human>: im im quebec canada (location for the bot)

pretty much, on the side i had merchandising jobs. i get contracts from time to time. this one was $125 flat rate per store completed. the scope of the work was 4 hours per store. 

they are arguing because i left a pallet with left over promotional material where i first got it that they had to send someone in to fix my work (literally close a box on a pallet). 

they are saying they will only pay me hourly vs the agreed upon flat rate.
so i should of made $480 and there only going to pay me 320$. 

I took 2 days off my regular job to complete this, as it was supposed to be a nice pay out for 2 days work. 

there waiting for a confirmation email that i agree to the changes.

Give me the gist of the text in a nutshell
<bot>: should of been paid $480, they only want to pay $320 because they had to send in a second person, to fix a pallet.
