Terrible service

Worst service provided by webuycars riverhorse, yesterday the 24th Jan, I returned a vehicle taken on finance on the 7th of Jan due to an issue, I was advised by the manager he will started the cancelation process for the old vehicle to be completed by Saturday and the new application for the new vehicle will be done on Saturday, today i went in, when they opened, to me finding out there was no cancelation done, due to the negligence of the manager, and they can't assist any further as the manager is off, the manager messed up, they should be able to sort it out, however the second in charge doesn't want to do anything, then they decided to sort the application for the new car in the meantime, however the Finance lady Kirusha kept saying she is to busy to assist, while the other finance lady in the office does nothing, they finance lady kept on assisting new clients and didn't assist us, so now I need to wait till Monday for the vehicle and take a day unpaid due to there negligence, I came from Newcastle to this and had a very little time to do this from Friday till Sunday, however the staff at the branch got no customer service experience, they need to go for training as it is terrible that a client is pushed from pilar to post to sort out something
