Slaughter and Fox: FRAUDULENT

I won a couple of sunglasses on several auctions that were listed on Bid or Buy (BoB) on the 8th of July 2018. The shipping and payment instructions on the listing where "FREE SHIPPING". When the auction closed i made payment. A day later the company contacted me saying i needed to pay R1124 extra for shipping or fetch the order from their fullfilment centre in Midrand Gauteng. I live in Cape Town. I wrote back to them stating that they were breaching terms of sale as this was not stated when the auction was still running. It turned out they had changed the shipping and payment instructions on the listing after the auction had closed. They did not reply back to me. I contacted BoB on the issue on the 10th of July and alerted them on what was taking place. BoB confirmed that indeed it was supposed to be "FREE SHIPPING". BoB wrote to Slaughter and Fox on the same day requesting a response but it seems communication is falling on deaf ears. Such business contact is unethical. I would not recommend dealing with this company. They are dishonest and can not handle queries in a timely manner.
