KFC Northmead!!!!!

I ordered zinger wings from MrD foods and I bought them from KFC in Northmead square ,they sold me zinger wings that tasted very funny and after eating them the is an after taste and they were not even hot I requested for an exchange or a refund and guess what??Mr D foods offered me a voucher for R35 for my next purchase ,it’s not even half of what I’ve spent.. After numerous emails of requesting a refund,I was ignored ..
