The worst service ever encountered in my life

Firstly they didn’t me that I won’t be getting the watch I purchased until the courier guy delivered a package without my watch . When i enquired they told me the realised on the delivery day that the watch purchased was fault therefore can’t realise it . Then they refunded me into my account profile and when I told them to refund my money back into my back account they said within 1-4 days and that was on the 26th of Feb and today it’s the 5th of March and I haven’t received anything . The watch was meant to be a birthday present so now I don’t have the watch and I haven’t been refunded!
