Bad attitude, rotten food and no response!!!

On the 2nd of January I complained about the expired and rotten food on the shelves at Spar Doringkruin as well as the bad attitude of the owner towards his customers. Since then it has been 13 days. On 6 January customer services responded and said that they will contact me within 7 working days so the 7 working days has passed... I received NO FEEDBACK!! I think this shows that Spar as a group condones bad behaviour, shouting at clients and the selling of rotten and expired food because NO-ONE made an effort to address the matter. I can imagine that if other clients had the same treatment as I did Spar will be out of business soon... I would much rather buy from a retailer that is a few extra km's for peace of mind and good service!
