STILL NO FEEDBACK

Its been one week since I sent Nandos Head Office a picture showing and indicating the I found a toothpick in my rice upon my visit to Menlyn Mall 2 weeks ago, I received several calls asking for the picture but to date no apology from nandos management and no feedback as to whether its been resolved, I have been very patient but it appears that they only call when you post on a platform that is public like this, I emailed them yesterday asking for feedback and why I have to chase for feedback no reply. It ridiculous that I have to resort to posting this on hellopeter to get a response from them. Finding a toothpick in the rice is a very serious thing, It looked like it was used for one, it was unhygienic & two, if I did not see it as it was embedded in the rice, I could have swallowed it then what would have been the consequences then, to 'highlight' of it all was to call the manager and for her to insinuate that we put the toothpick there? Explain to me how this is okay?
