Mayfair Gearbox Germiston don't pay their suppliers!

This company booked it's staff in to stay at our Guesthouse and paid weekly for a few weeks. Then after extending for a further seven days the three gentlemen checked out three days early. The company notified me of the early checkout and requested the final invoice. This invoice was never paid and the company then claimed that the staff member who had been making the bookings was not authorised to do so. This same staff member had made all the bookings over a period of six weeks on a Mayfair Gearbox official email. The company then "offered" to pay 50% of the remaining invoice in order to settle the account. It is not our business practice to allow our customers to negotiate rates after the fact and this company was certainly aware of our rates since they had been booking and paying for our services before. This is unprofessional behavior and extremely ********* business practice by this company and i urge anyone who deals with this company to insist on payment upfront!
