Beware hidden charges from Stikets / stikets.co.za

I purchased name stamps for clothing at a total of about R1200 on stickers.co.za, it said delivery free for orders over R800, no mention of this coming from overseas and that it was excluding import & customs clearance charges, I have now been told I need to pay a further R800 in order to clear and receive my stamps 😡😡😡
