Upset customer

I bought a BBQ chicken at Bethlehem Woolworths on Monday. Me and my husband ate some for supper. Monday evening we end up in the ER with vomiting and upset tummy. I took yhe rest of the chicken back and the manager took my details and told me they wipp be in contact. I also send an email to Woolworths and receive a reply " Thank you for contacting the Woolworths Customer Service Centre. An agent will be in touch with you shortly to provide assistance." Up to today nothing.
