Poor Service from Manager at Meerensee Pick and Pay

Good day Could you kindly assist me, I purchased ½ a lamb on 28 June 2019, From Pick and Pay, Richardsbay, Meerensee, I purchased the meat at the final hour around 8 pm before the shop closed, it was such a rush for the cashiers to rush up, I never gave in my Smart Shopper for my points, when I left the shop, I approached the manager on Saturday, 29 June 2019, and he said he will sort it out, I approached him on 01 July 2019, and he is still busy to sort it out, so now I approach the head office if the can assist me. Or do I bring back the ½ lamb ??

Attached please find my slip and details of the purchase.
