Pick n Pay online delivery service is a joke

I placed an order on Pick n Pay online, paid R90 for delivery between 10:00 and 11:00, at 11:20 I started phoning Pick n Pay, again at my expense. At 12:00 the lady at customer care told me they can not get hold of the driver, no solution or suggestion as to how this issue is going to be addressed, just that the driver's phone might be off. This to me is totally unacceptable, not when I paid for a time slot, and the money has been taken from my account, 12 hours before the order gets shipped, and now nobody knows where it is.
