Raw Chicken with a spit in the face responce.

I ordered R110 worth of zinger wings from KFC via Mr Delivery. The chicken was raw. I logged a complaint on the app, with picture evidence. I then received an email requesting picture evidence, which i provided again. To which they responded with an apology and a R25 voucher. R110 wasted, and they have the disrespect to give me a R25 voucher, not even cash back, but a quarter of the value the I'm forced to spend with them again. Not acceptable.
