Not true to there word game store

Took a smart tv back that i bought 2 months ago. I live far from kimberly so went for Christmas shopping there. The tv stopped working a week ago i took my child to the doctor today in Kimberly and so had a chance to take the tv back to game store at north gate mall. They told me that they will send it in for repair or give me a voucher if it cant be repaired. I spoke to the manager and explained that i dont live near Kimberley and cant just return for a voucher or the tv if repaired. So he agreed to rather give me a voucher after waiting for about 20min in a warm part of the store because there system has a problem they booked the tv in for repair and told me that they will contact me if it is repaired.
