Suspicious Company

This company responds very quickly to an online query via WhatsApp. They informed me that they have exactly what I am looking for - at a wild price. We agreed on some samples. Then the suspicious dealings start: Their policy states that: any order amount below R2500 has to be paid making use of an E-Wallet account of the bank of your choice. Which company does that? When I confronted them about this, asking why they do not defend themselves on this site, they became VERY defensive and told me off as being a "bad customer". BE CAREFULL of this company - it seems like a ****...
