Taking my money without delivering

We ordered and booked a delivery for a specific date and time. 1 day later still no delivery and no call from pick n pay to explain. Order cancelled via call centre after holding for 20 minutes! Most shocking call centre ever! Agent promises to cancel order but despite this, they show up 2 days later with goods (half of which were wet!). We tell the delivery person order was cancelled but despite this they debited our card account with the order amount of the wet items and keep a pending authorisation on the account. To date not fixed and we can't get hold of anyone as no one responds to the emails and neither does their call centre answer the calls! Shocking! Will never ever order from Pick n Pay again. Worst experience ever!
