Tops Birchgate mediocre service

I visited Tops at Spar Birchgate on 26/12/2018. The service I received was beyond pathetic. My brother made a purchase of 2, 6x440 Windhoek cans, when we got home we discovered that a 6 pack was leaking, 1 of the cans had a hole and I decided to take it back as the pack was sealed and there was no negligence on our part in handling the goods. On arrival at the shop, I showed the cashier who then advised me to go to the fridge and look for a replacement. As I was in the fridge a tall gentleman approached me and arrogantly asked what I was doing, I asked who he was and he told me he is the manager, I told him what happened and he said he won't let me take any beer and insinuated that I dropped the beer because his store was not wet, which i rep**** if that was the case the cans would have been dented. I then told him that I did not drop the cans, in fact, he is trying to sell me damaged goods, he got upset and was shouting, at which I responded by saying I will take the beer if he has an issue with that he can call the police. He then caused a scene and 2 of his other colleagues came and followed me to my car taking pictures. None of them came to me to try and understand what was the frustration piont and see if we can come to an amicable conclusion. So I took the beer and left. I am reporting this to warn the public about Tops at birchgate management, they lack customer care and are pathetic in dealing with customer complaints, their only interest is raising profit margins.
