Pathetic Customer Service

I really had terrible experience at Spar in Flanders (Mt Edgecombe) the manager there his name is Terron if not mistaken his customer service is so pathetic he doesn't have a manner of speaking with customers he was so rude to us and pointing fingers as he was speaking with us he doesn't obey the rules of being a leader in the store the rudness was the worst I wonder how he treats the staff if he can treat customers like this....Spar please do follow up before I take the matter to social media
