Rotten pork schnitzels-Manager refused to exchange

I bought a pack of pork schnitzels from the Woolworths on Lynnwood Road. Cooked half of them. They were clearly off, looked green in color inside and smelt bad . Rubber texture , not even edible ! When I returned the uncooked portion of schnitzels to the Woolworths today -I was told by the manager HIMSELF to \ cook the other half and see if they are also bad". He then proceeded to ask me \"" if I followed the cooking instructions \"" while pressing his finger on them and said \"" these ones don't look bad \"" and that \"" they have not had any problems with the schnitzels before \"" .<br> I insisted on an exchange "
