7 Times finger trouble

<p>Okay so this might be a bit confusing but anyway. i recently bought some parts from ferobrake to the amount of R9453.72 ( invoice number 33088) note the invoice number, when my driver goes to pick up the parts, Already paid for via EFT. he gets an invoice for R7453.72 (invoice number 330084). (note the cheaper invoice was first) anyway i called the store and spoke with the sales person involved and the bookeeper and the manager who claims it was finger trouble to the tune of R2000.00 and they dont want to refund. </p>
