Contaminated Koo Butter Beans

On the 21 March i purchased Koo butter beans. Upon opening the can i found a foreign object, i then contacted Checkers where the can was purchased and they then were following up with Tiger Brands . I posted on Tiger Brands fb page and on the 1 April they asked for contact details which were given, to date no word from Tiger Brands. Checkers asked me to keep the can in case Tiger Brands wanted to pick up the can, i kept the can but a few days later it got rotten, green and moldy in my fridge. It was not something small in the can it looke like piece of sack squashed and rolled up amd put in the can. This was negligence in their canning process and thats why items are been recalled because of contamination. Koo butter beans has been off the shelves for months and now there is a major issue which Tiger Brands fails to acknowledge. Is the service one should receive from thus company and how is their hygiene during their canning process. Most disgusted really.
