Terrible customer service

On 21 Sept I ordered an item online for delivery to my house with assembly. Nearly 2 weeks later, they deliver it to the store claiming I entered the incorrect address and that the onus was on me to ensure correct delivery address. So I asked if they could deliver it to my house. The answer was no but they would send someone out to assemble the item when I fetched it myself. So I requested a refund. A month passed with no refund. I called / emailed etc. Subsequently the card I used to pay for the item was cloned with I was travelling. I advise them 3 times of this and yet they still allegedly attempted to refund my card. Yesterday, they ask for banking details. Today it is not possible to refund directly into an account. I must provide the old credit card details and give out my new credit card details over an email. Beyond frustrating experience to get my money back for an item I never received.
