You say "I have refunded". If that should be "I have been refunded" then the original ebay label won't be available now. When a seller refunds upfront ebay assume they don't want the item back and remove the label. Often the seller has just made a mistake but they do then have to arrange the return themselves. Your refund cannot be retracted.
If that's not the case ask the seller why they have arranged a different collection. The process should be kept on ebay if you haven't been refunded yet.
