Car fog lights

I purchased a set off fog lights for my car As advertised R250 for white 30 watts light Twice returned the lights as 10 watts light delivered 3rd time received 10 watts light again which is advertised for R180 Only realized it was the wrong light after having it fitted to the car Request for to be credited to me Takealot refused quoting their return policy How was it possible to deliver the wrong item 3 times 30 watts light is not advertised on their site anymore In all fairness I think I should be credited the difference
