Fungus on mini loaves/ bad service

2nd time I bought mini loaves and all my loaves has fungus on. Sent an email to KFC and informed then. 2 days later they emailed me asked for my phone number. Sent them my phone number and said I'm not available on my cell between 8am and 4pm weekdays. 5 days later sent another email asking what they are going to do about this and I haven't heard anything from then since they asked for my cell nr. 2 days later I got a call from Paarl KFC, but wasn't able to answer as it was between 8am and 4pm as I stipulated in the email. Phoned them back after 4pm. Manager who was looking for me said it was regarding my complaint and she will phone me back. I waited another 5 days and no phone call. Sent another email reporting their bad service, as she promised to phone back and never did. 2 days later she phoned again, and still during my working hours and she left a message saying I never answer my phone I'm probably busy. But she doesn't mention the fact that I did phone back and she promised to phone me rather, which I probably would never have heard of her if I did not complaint again.
