Stinking wings

I went to pick n Pay sanridge and bought sticky wings, pap and sweets on the 22 August 2017 only to find out that the wings are expired and are stinking.... I send an email to the owner to let her know about it and requesting reimbur*****t even today she never responded...this means she support this. Can someone assist me with details of the franchisors of the store so that I can take this further
