Very bad customer service from Mellins Fourways

Such bad bad bad customer etiquette from the fourways branch. When I initially went for my eye test I spend more than 2 hours while they were trying to figure out if I had savings on my medical aid or not. When it was time to collect my glasses I spent another 2 hours , them trying to convince me that I own an amount that didn’t reflect the breakdown that I got from medical aid. Called my medical aid to confirm that I was not owing anything but the optometrist told me that I should speak to medical aid to call them. These people have no sense of business or how to treat new clients. Too bad for them that they will never see me. But I still want my refund
