Beware of selling on BidorBuy!!!

Last month I sold 4 items on BidorBuy. The total sales generated by me was R9800.00. After being told that the funds will be paid out the next day I have sent two of the items out. Then I received a phone call out to tell me that I must send these expensive items out at my own cost and await for the clients to receive the goods and be happy about the purchase. This month I sold an item on BidorBuy, the payment was made by the client and for some reason I cannot withdraw the funds!? I am seriously tired of BidorBuy's ****py attitude towards me as a seller and I want to warn everyone to rather never sell anything on their website. I will not send any items out without firstly receiving the funds for it. If they cannot understand this simple fact or have some nonsense excuse like they allways do, then I will close my account and rather buy and sell on a much better platform!
