Won't take items

Cash converters aren't the place to sell things they give very little for what u have all tell you well cattle to sell it. Like they want u to give items away for nothing. Was told a centurion they take plastics etc when I took items to Morleta Park cash converters. For all plus glass dishes was told they'll only give me 85rand. Took my items gave to charity shop. Cash Converters are the biggest bull****ers out there..
