4th time and I never learn

Good Morning. I just want to start off by saying that this is the fourth time that this happens to me at the same branch. Last night i bought food at Nandos in Allens Neck to the value of R150 and what a waste. Firstly i waited in the drive through for more than 20minutes before odering the food, oh this is also me idling the car as well, then i ordered the food and was told to move over and wait a bit longer because i wanted my half chicken well done. so i did this. I asked the guy who took my order and brought it to me while i was waiting out in the front to make sure that my chicken is well done and that when i get home i wouldn't have to eat wet discusting chicken... Guess what when i got home, there it was a wet half chicken that was so under cooked... i threw it away and ate only the roll with the sauce... My fiance's spicy rice and chicken strips was very nice except the fact that we paid R8 for extra Feta cheese and guess what, when we got home there was no Feta... I was not willing to waist my petrol and go back and complain. I want this sorted and i want my money back because this is dinner time *******... I will be going back there this afternoon to demand my money.
