MTN Herm**** complaint _A|_ bad sales person

Hi,<br> <br> On 18/05/2015 I bought a car charger for micro usb connection at MTN store - the Herm**** station while on holiday. The sales person was Linda Whiteman. I tried it and it did not work on my car. A few minutes after my purchase I returned to the store telling her the reason for returning the item. She looked at me puzzled as if she did not even know I bought a car charger saying I bought another item and was almost argumentative. I took it out and showed her the slip. She took the charger and stormed out to her car showed me it worked and went back to the store refusing to let me return the item. In no way at the purchase point did she mention I could not return the item and the slip also does not state that. <br> <br> I went to another MTN store part of the Cell network recently and they say I need to go the Herm**** store to return the item. This is ridiculous as this product does not serve my need. The sales experience I received from the sales person in Herm**** and not being able to return the product - which is still in a saleable condition, is the worst sales experience I had as this definitely diminishes the service of the MTN.<br> <br> Please advise what actions can be taken?<br> <br> Taariq
