Terrible Customer Service

On the 30th of June, I placed an order for a fridge online. After a couple of hours I went to the store to actually view the product and I was not impressed with the size. I immediately cancelled the order which was still "In Progress" on the order portal. Later that evening after cancelling the order, I received an invoice - sighs. Saturday morning, I called the call center again and also reached out to the social media team again to just confirm that the order was indeed cancelled to which they reassured me that it was. An hour later there was a delivery attempt to which I told the driver that I have cancelled the order and therefore cannot accept the delivery.

Now, 4 days later I am receiving an sms from WUMDrop that a delivery has been received by me. Funny enough, I am not at the house and there is also no one to sign for the product. Secondly, the order has been cancelled so how is the delivery still being facilitated. Thirdly, nobody has bothered to confirm when my refund will be processed as I do not need this product anymore.
