Overcharging

Just want to warn people about takealot they charged me more for an item than what it was advertised for. The item was advertised for R237 when i put it in my cart when i was done shopping i paid without paying much attention to the details which is my fault but i fought i could trust a place i am buying from for years when i got my confirmation order from them my eye caught that they charged me R278 for that item i went back to the site to make sure and the item was still being advertised for R237.After contacting them several times i got this answer a week later from Monica B 'Our third party party sellers use our website as an advertising medium for they products and their pricing their items is up to their discretion' now who doesn't know that. The fact is when i bought the item is was advertised for R237 then i was charged R278 (by the way should you not be warned if an item price might have changed while you are still shopping) for it while is was still being advertised for R237 after i bought it. Now there is only silence from them. I only caught it because it was such a large difference so who knows how many times they might have done this to me or you
