First online shopping experience - taken my money but no delivery and no communication!!!

Did my first online order last week and the timeslot for delivery was yesterday between 11h00 and 12h00. At 14h00 I called Customer Care to find out where my delivery was and after holding on for a long time Andile said she would call me back. At 14h24 I received an email to say that my call with reference to my late order had been completed. ??? Still no delivery. I called again at 15h15 and was told to hold on and then I was cut off. At 15h45 I called once again and was told that they had not been able to get hold of the store that was doing the delivery so they could not update me. I asked about the email and was told it was because Andile had opened my order file.??? I then received another email at 15h54 to say that my call with reference to my late order has been created and will be actioned. It is now 10h00 on Tuesday and besides the two emails I have not been contacted about my delivery. I find this totally unacceptable as they have all my contact details. The money for the online purchase was deducted from my card yesterday morning and Pick n Pay cannot tell me when I will receive my groceries. I think this might just be the first and last time I order online from Pick n Pay!!
