NO EXCHANGE at Unimart shop

I bought toys at Unimart store located in Secunda square, the problem is you can't open and see what is inside as they are not allowing that; at the same time they don't exchange. I bought toys yesterday when I arrived home I saw the quality of what was in the box is very very poor, I then decided to go and exchange they refused. They don't want to know the reason you are bringing it back. Who knows they want to get rid of it... Please be ware of that shop they are cheap but do not have customer care.
