Ok stores

I bought best buy beans at the ok in Durban Olympia junction center these beans were off the has a grey substance on top and tasted bad when consumed I had consumed one tin I open the rest but it was the same I took it back to the store and informed them about they contaminated tin stuff I told them I was sick after I had eaten one of the tins went to the doctor and hospital due to illness I was told to call the manufacture best buys I did but the lines were all cut buy they agents when I told them that they goods is off and I was sick I also emailed them about 7 days and have not gotten any response from them. When I looked at the ok store paper they had the same beans on sale even after reporting the 5 from the 10 I had brought was off I'm not sure if best buys and ok are trying to kill us black people with these cans but please stay way from any best buy products sold at ok store they could be deadly I was hospitalized for eating they contaminated tin stuff
