Disgusting customer care at Spargs Spar Beaconbay East London

Shopped at spargs beacon bay east london. Part of my groceries were 3 x eggs.One of the brands was sunrise. Noticed that the other brand where i bot 2 eggs (18) was rotten inside. So I returned them,the 18. Unfortunately I did not have a slip, but fortunately I had paid with my bank card . They managed to retrieve my slip form thier system Called Sigma which showed all items I bot on that day... when it was time for a refund, Brett who is said to be the store manager refused to refund me for the rotten eggs as he stated that I did not produce the egg cover sheet which is placed on the eggs which shows the name of the eggs and which supplier they belong to... I said all that information is already on the slip he had printed for me. He then told me it's thier company policy to have the branding paper when returning the eggs. Asked how possible is that to keep the branding of the eggs as well as the plastic wrap as I store my eggs in the fridge in a plastic egg container immediately when I arrive from the store after I buy eggs. He bluntly refused together with his colleague a lady named Doreen who was the 1st person I spoke to on my arrival Before I left he said to take my contact details and will pass them to his Manager Travis Vincent to call me ....... I have not recieved any call from Travis Vincent since the weekend 04 04 2025. Today is the 08.04.2025. I was then forced to go back home with there rotten eggs from Beacon bay bay to gonubie where I reside...now I have lost money buying rotten eggs from them. this is poor customer care and I'm extremely dissapointed at the store manager for him to refer me to his manager when he is the one appointed to handle such when directors are not around. Poor management and customer care skills I am disgusted and I want my refund.
