When a good service is provided it deserve a compliment as same when a company is providing a bad service, it is a right of a customer to share that so the the company can fix it to become better. I saw the best company going from being the best to the worse, reason is the do not value customer service. My name is Vuyani David Biyana. Last year I bought a items at Online Car Parts and I was happy because my items were delivered, but one item was wrong and opted for refund. I have been calling and chatting with the agents, till today. I have not received my refund. I spoke to Nicky, Vanessa and Nkosimoyo. I even tried to opted to buy items with my refund, but the items the are either expensive or not in stock. Can someone who still value customer service or who believes that if a service is not provided a customer has a right to receive their full refund on 24 hrs min and 72 hrs max
