POOR SERVICE

About 1 1/2 mnth ago I bought take-out from Nandos. I ordered Mild and was instead given either hot or extra hot. I only had a small piece of it and disposed of the rest. I had food poisoning and had to get medication for the food poisoning(doctors where closed on Sunday). I immediately contacted the Nando's manager and explained my case who then referred the case to the Customer care Dept. After that day I called in 3 times and had to even visit the store once to find out what conclusion they had come to. I received no response until 2 weeks later when a lady called me informing me that they had investigated the store and found the food to be of standard. I said to her that there was nothing wrong with the food but negligence on the part of the staff. This was not investigated. I was promised that I would receive something in the post as compensation and its now been 3 weeks and have received nothing. I am upset that firstly my initially issue about the negligence was not looked into. I suffered for 3 days due to the negligence of the staff. Secondly I had received no feedback during the 2 weeks I waited. Thirdly the service and promises made to me where never kept.
