Clicks Online Orders, Double debiting and failing to deliver or refund.

I placed an online order on the Clicks website on 17th Dec 2018 for baby items. They double debited me for the transaction, advising that the payment had not gone through and that I should contact my merchant. The order was not delivered, and they advised me that there was a technical issue only after 7 days of me enquiring. I cancelled the order and was advised that I would get a refund for both the cancelled order, and the double debit. I am still to receive my refund, and have been advised that It would take 17 working days again upon me harassing them for this information which they are not forthcoming with. Their system is so quick to deduct and have the ability to deduct twice yet cannot have the same urgency in refunding our monies back for orders they cant process or live up to. I am disgusted, I live in a different province and these were urgent items that I needed to purchase for my toddler I cannot wait 17 days for a refund on top of the 2 weeks that I waited for the stuff to be delivered. This is unacceptable
