Misleading terms

Misleading customers on delivery terms. Website said free delivery for Gauteng on orders over R500. My order was over R1000 and on checkout they added R262.50 delivery charges for Pretoria region. When I phoned them they said delivery is only free for "Johannesburg" and Pretoria deliveries are R90. Later on terms it reads Pretoria delivery R90 (for orders under R500), but they still charged R262.50 Be carefull!
