WORST customer service ever

We went to buy the lamb special at Pick n Pay this morning and stood in line for 2 hours with no assistance. People who arrived way later then we did got their lamb immediately and we realized that it was the butcher's friend. He gave him 4 whole lambs while it stated clearly on the adverti*****t in the shop that only 2 per person was allowed. Then all of a sudden people who phoned and ordered the lamb got help first. Nowhere did it state you should order the lamb!! I thought it's first come first serve! I went home and phoned Pick 'n Pay and ordered my lamb. I went to collect it at the butchery and stood in line for another hour and a half. We asked the lady with the order list to please make sure that our names were on the list so that we dont have to stand in the line for nothing. She completely ignored us and fetched her friend's lamb who stood LAST in line! We went to see the manager twice and his response was that he didnt believe that the service was as bad as we make it and that he will take our number and call us if he sees our name on the list. 3 hours later and NO call. We left Pick n Pay with no lamb! The service is beyond terrible and I will NEVER shop there again!
