IQF 15% BRINE CHICKEN BRAAI PACK 5KG ***

I was promised a R300 voucher by pnp after I found a foreign substance in their 5 kg no name chicken brand, this promised was made on 7th of November, that the points for the voucher will appear within two working days, Five working days has gone past, nothing and they are not even responding to my emails, I am of the opinion that the promise was made to silence me.
