Disgusting service

My son turned 15 on the 30th of April. We visited Lone Wolf Spur in Randpark Ridge. Our waiter was Phana. After taking our order we told him that its our boy's birthday. When the meal arrived, the burgers were dry, like it was standing out for a while and it was warm. My son's ribs and chicken got cold quickly because we sat outside. We waited for 15 minutes before we can find someone to get our food warmed. Phana had disappeared inside and was nowhere to be found. The lady that did take our food left it at a nearby table so she could sing happy birthday for another customer. Our meal was not a priority even though there were plenty of waiters around to sing for that customer! So that was another few minutes. The food was gone for another 10 minutes until Phana came back and we had told him that we couldn't find him and that we were waiting for our meals to be warmed. His response, yes I know. It will be here just now. No apology, no interest in making our experience a better one. We waited another 5 minutes until the Manager, Sello brought us our food which by then was warm. This was by far the worst experience we have ever had at a Spur. Phana did not even arrange the waiters to sing happy birthday for my son. Such pathetic service. Totally disgusted. Total waste of money. It was an important day for our family and this experience ruined our day!!
