Pick n Pay unreliable

I bought groceries on line from Pick n Pay and selected click and collect. I went there this morning at 11h00 to collect my groceries only to find 2 hours later that it had been picked but not captured. I then phoned on line support and they told me that there was no bank authorisation. I then phoned the bank and gave the phone to the pick n pay manager to tell him the funds had gone through and there was no problem. The problem was that the manager had no one to capture. I then left with no groceries and am still waiting to be contacted.
