Unacceptable and unprofessional

Extremely disappointed with Nashua Worcester. A sales representative visited our rural school and quoted us for a new machine. However, when the bill arrived, the amount was suddenly increased, and he has been offering a range of excuses for why this happened. Despite contacting the manager, to address the issue, no attempt has been made to correct our account. Instead , they`re now trying to push phone systems on us. The sales rep keeps making excuses and refuses to amend the bill, claiming he has to factor in operational cost after the quote was issued. This is unacceptable and unprofessional.
