Terrible customer service

I bought bedding on the online sale and delivery was suppose to be on the 11th November. That afternoon I received an email say that they could not deliver due to an incorrect address. I emailed them back with my correct details and also followed up with a phone call. The lady took down my unit number and contact number as I live in a complex and said that they would deliver. Yesterday I called again as I did not receive my order and the lady said that it hasn't been sent out yet and she will follow up. Today I get an email to say that they will refund me. I want my order and not a refund. Why didn't the driver call me as they had the correct address initially just not my unit number? Also I did reply immediately on Monday to add the unit number and no one followed up again. I work from home and if they called I would have walked outside to fetch the order
