Pathetic online shopping experience with Jet.

I placed an order (# ********** 51) last Thursday 12/10 for which I could have either chosen free delivery anywhere in SA (10 day waiting period) or pay a delivery fee (0 day waiting period for click and collect) according to the website. I chose the click and collect option and paid the required delivery as I did not wish to wait for my order. After finally being contacted by Jet Head Office, I requested that I no longer want the order to be delivered to the selected store and would like for the order to delivered to me and for delivery fee to be refunded. I was told by Lucky that this would not be possible as the 0 day delivery for click on collect was a "system glitch" and that order was already dispatched (on 13/10) and is with the couriers to be delivered today or tomorrow to the store for me to pick up. However, on Monday 16/10 I received a mail from Jet Customer Services stating that "the order is at its packing stage." - Online shopping is not meant to be a hassle! Surely some arrangement could have been made on their side to get the order delivered to me and not the store.
