Online order delays and only informed late about card problems

<p>On Sunday I purchased groceries online for my grandmother using my credit card. A card that i knew would expire on Tuesday. After making the purchase and processing the order with that card i got confirmation that all was successful ie my bank had approved the purchase etc and that the groceries would be delivered today between 12-13h00. On Monday i called my ailing grandmother who lives alone to tell her that her groceries would be delivered today. To my surprise at 14h38 i get a call from Pick n Pay online saying that they are only processing my order now and my card is being declined. How? i asked, considering that everything was confirmed on Sunday and i relayed the information to my grandmother using the confirmation received from Pick n Pay? well, we only process orders on the day of delivery? But this is 14h38 and my grandmothers food was supposed to be delivered at 12h-13h00. What kind of inefficiency is this? So what now i asked her, especially because this is now extremely urgent as my grandmother does not have food or a person to send to get her food, her nurse only comes on week-ends. I was told i can only do a purchase with my debit card if my debit card has an electtronic signature. I HAVE NEVER BEEN THIS FRUSTRATED BY SOMETHING QUITE SIMPLE, an online purchase! Incredibly inefficient on your end because what this means for me is that my gran is going to sleep on an empty stomach or with whatever she can pull together tonight and possibly tomorrow or until i receive a new credit card from my bank. if i ever purchase from your stores again when you have inconvenienced my grandmother like this i'll be damned. </p>
