Service not rendered

We hired a bus from Transbus and paid the full amount. Their driver didn't show up on the day and we were later informed that he got lost, so no service was rendered to us. They now want to involve us in their own internal processes with the driver and that is non of our business. We requested a refund from the company and nothing has been done two weeks later. We went to their office yesterday and were promised the refund would be done by the end of day but that too didn't happen. Following up on our refund today and we were told management is not in today and the finance lady is off sick. Their excuses to process the refund is never ending. Transbus customer service is Non Existent, all the care about is money going into their bank account. Beware when dealing with Transbus Africa
