Failure to deliver service.

Placed an order at 2pm which I was told will be delivered in about 30-40 mins. Around 3pm I called again they told me the driver is 5 mins away. I waited another 30 mins, called again at 3:35. My order was still not delivered. And the manager kept apologizing telling me that the driver has arrived and is waiting for me outside. When I asked why the driver hasn’t called me if he’s here, the manager couldn’t answer me. I found this very unprofessional as I am a regular customer with them and I do not expect such treatment and it wasn’t their first offense. The first two times I gave them the benefit of the doubt as they had done this before. One other time they even delivered ice-cream that was off to me but I still have them the benefit of the doubt. This is really unfair treatment of clients.
