Lack of service and customer acknowledgement

The drive-through service was terrible and service appalling. You get to the intercom, and no one is there until you hoot then get to the window to pay no one is there to accept the payment. Waited for over 7 minutes and you see the staff just walking around however no-one assisting. Another car came, and then I moved to the next window as that window got opened, so I assumed they would help. They couldn't apologize for their horrible service or acknowledge that they at fault and I was told to go around to be able to make a payment and the lady mending(Zanele - I heard as they casually called her) the drive through would not come as she was called by her colleagues. Poor poor service.
