Unanswered Phone for delivery

Restenburg Square Debonairs pizza, what is the point of having delivery when you don't pick up the phone? I went there on friday, steamy as it was in the store (I fear for your staff's lungs), & yes it was very full since it was month end. Then on saturday, i called multiple times without the phone being answered. Decided to drive there personally, it wasn't as full as it was on friday, and to my shock, the phone was ringing and no one was answering. If you are going to have a delivery services, please be sure to provide that service or just cancel it.
