Worst customer service I have ever experienced by the Samsung Canal Walk store manager Yolanda Jacobs

My brother booked his phone in for repair via Samsung Care for the Samsung Canal Walk store and I took it to the store to get booked in on Wednesday, 21 December. Samsung Care didn't give him any other instructions as to anything else he may require in order to drop off the phone so I was sent on his behalf to drop it off before we would be leaving on holiday early the next morning as he wouldn't have time to. Canal Walk is not on my doorstep so upon my arrival at the store to just hand in the phone to get repaired, I was told I need the contract or proof of purchase of the phone to do so. We explained this wasn't stated as a requirement and received the worst customer service I have ever experienced in South Africa from the consultant and an *********** and rude manager who has no people skills whatever named Yolanda Jacobs. This is not my first encounter with her siding with her staff without understanding the full story and trying to resolve the issue and help the customer. Never in my life have I been chased out of a store by a manager like I was by her. She doesn't deserve to be a manager and is a pathetic representation of the Samsung brand. I then called the Samsung Waterfront store who without hesitation and such good customer service took the phone to be booked in without any hassles and I was told that the contract or proof of purchase was never required as the damage to my brothers phone was physical damage caused by himself. We have always been loyal to the Samsung brand as a family and not only limited to mobile phones but for a customer to have their time wasted like this without taking the phone to have been repaired is shocking to say the least.
