Takelot fails to take responsibiliy for products.

I am making a complaint against Takealot on behalf of my employer. My employer has has been without a working GPS now for over 4 months, after it was sent back to Takealot 3 times. This Tomtom Via 120 has problems such as slow performance, freezing up on the start-up screen and a faulty USB cable that was given in one of the returns. No matter how it has been stated to Takealot via their customer service and a letter that was written to Wayne Leverton (the head of customer service) that is particular model does not function properly, Takealot is intent on returning a new product of the same model to my employer instead of just honouring his wishes which was to receive a credit to his account of the money he spent on this product. It has now been about two months since he has heard anything from Takealot and due to this incident, he is far from impressed and where he once was a happy Takealot customer, he will think twice before buying from them again.
