contaminated beer

I had bought castle lite from my supermarket and found that there was a rattle in the can I contacted the supplier who was more interested in me seeing the brewering process than handling my complaint. It took 5 calls for them to pick up the product and send it for testing. They told me it would go to an independent lab but all testing was done in house I asked for a microbial report and was denied it even after telling the gentleman that I was booked off sick after drinking the product Mr niaker then imp**** that I was telling lies and that I was intoxicated when this happened and is refusing to take responsibility I have called sab customerservice today and was on hold for 15mins I called the head office and everyone seems to not be in their offices today this is really unacceptable for a company this big to treat their customers in this manner and not care about their complaints
