Misleading Customer Service

On the 25th July I ordered a pizza from Debonairs Langa Junction for delivery at work. After two slices I found a hair embedded in my pizza. I struggled to even pull it out because I wanted to ensure it had not flown in maybe where I was sitting. It most certainly could not have been mine, since I have braids. I took a picture and sent it to Debonairs. They responded and requested my contact number and what my order was. They said they would call back. Come the 29th July, no call, so I sent them a message again. They responded on the 30th saying they are sorry they will get back to me soonest. Fast forward to the 07th August, still no call. My question is why even bother by lying and saying you will sort something out, they should have just not responded to my message, that way I would be more accepting of their ridiculous customer service and yes this is going on my FB and Twitter, I will assist in advertising the ridiculous careless service they provide.
