Sub woofer

I have never been soo disappointed In a store like i had with cash crusaders at atteridgeville..the store can't make a simple thing by just giving back my money back for the product that is not working..the roundabout with the store and their communication person has been nothing but disaster..I wouldn't recommend anyone to purchase any product from that store because u must know that you wont get your money back if it is at fault..the customer service there is very bad...they do not or should I say qualify to render service to people.
