The dispute button appears after 9 days from when the order is marked as sent so you'll need to wait if it's not yet showing.
If you haven't yet done so, get in touch with the vendor as most issues can be resolved without a dispute. If you can't get a response or agree a solution then use the dispute button once it's available.
