Nandos *****s from me again

We decided to give Nandos a break after our experience with Nandos Rooihuiskraal in Centurion, messed up our order by not putting everything in the bag. I put a comment on hellopeter and they ignored it. So after 3 months we decided to give them a try again . Low and behold same mistake. A piece of quarter chicken was missing from the grande meal. And we paid for it. I phone them, same excuse we don't have drivers. Phoned customer service..we will send you a reference number. It's like these people pick my name out of a hat. So they are essentially *****ing from me. If you ***** a piece of chicken from every customer...So what are you going to do about this Nandos. ***** the money and keep quiet.
