Smelly meat

Few weeks ago we went to Devland chicken liken, and bough 12 Hot wings, only to find out that the had a bad smell. Unfortunately we noticed when we were already far from the restaurant. Out of the 12 weeks, 3 of them had this smell, it was like the meat was rotten. Last week I went back to buy wings at the same place since i stay in devland, when i enter the restaurant the whole place was smelling of the same smell i came across the other day ,my husband told the manager that this meat is not smelling nice and he just looked at him and left, we decided to leave and not buy. Yesterday ( 28-10-2015) we went to Bara Chicken linken, i bought 6 wings and 2 of these wings had the same smell i came across the last time. This is a big issue cos now their selling us rotten meat. we cannot enjoy what we have purchase without coming across a smelly wing. Something must be done with this.
