Bad service from Nightsbridge and Booking.com

When I first heard of Nightsbridge, I thought this is just the answer for our small selfcatering business. During the first few calls and mails, the staff were so friendly, helpful and patient. I felt so at ease and happy. Then the problems started. They suggested we link up with almost 100 other booking platforms - one of which was booking.com. They even offered to do the registration for us - how nice! Not too long after that we got our fist few bookings from booking.com via Nightsbridge - but we never got our money! After several requests and now suddenly very poor service, we were told the reason is that we should have arranged a card machine to swipe guests cards when they arrive. This was never told to us, we do not have a card machine, and we clearly indicated we only accept eft payments when the booking is confirmed - like it is done by Airbnb and Lekkeslaap. Not to long we also had a double booking! Again booking.com via Nightsbridge. We originally cancelled the booking as soon as we received it, but later learned that the cancellation on Nightsbridge means nothing - we were suppose to go and cancell it on booking.com as well...what kind of service is this? We were under the impression Nighsbridge is there to prevent just this! We are nou missing the money of 3 stays by guests and not Nightsbridge or Booking.com are helping us. The mails and calls are not answered and the friendly staff are all gone! PLEASE do not make the same mistake as us! AVOID NIGHTSBRIDGE and their friend BOOKING.COM!!!!
