SPAR 2U ******

I purchased from the deli on Spar 2U cooked lasagne that arrived uncooked and inedible on the 20th of August 23. I immediately complained about the food which they then collected from my home. It cost me R125.99 on which I also paid a 10% of the purchase price making it approximately R138.59. They only refunded me R49.62 and I've been trying to get the difference refunded to me to no avail. I've spoken to Eunice, Francious and Gary and the last contact I had from them was the 1st of September in which they advised me that they have logged a call with head office. I still haven't received an update or refund from them and now my messages on whatsapp isn't going through, it seems like my number is blocked.
