Bad dealerships

I am so disappointed as we received an offer to sell our Honda Jazz and were told to meet the dealer in Pretoria, Tjaart! He arrived late after we took our time and another car to bring us home, only for Tjaart to reneg on his offer! I am sure he was trying to get us to negotiate to a lower figure, this is in bad taste and not according to the rules of Weelee? We have not sold this vehicle at this stage. If Weelee are going to allow dealers to treat clients like this, I will not be using this platform to sell my vehicles going forward!
