The accounting department of this company is the rudest, most unprofessional and unresponsive one I've never dealt with. They didn't identify the payment I made and mucked up our business's account. The problem remains unsolved despite my efforts of calling and emailing and providing the documents they requested. When I called the accounts again today to discuss the issues, the staff couldn't answer my questions but just hung up on me. Unbelievable!
