Sorry, we are members like yourself here, but no one can speed up the refund process, and it does depend how you paid, as to how long it takes to receive that refund.
Once eBay notify you the refund is made, being processed, then it's not instantly returned to you, and does go back to original payment source.
If you paid with PayPal it goes back to your PayPal account fairly swiftly.
Paying with a debit / bank card? Can take up to 12 days to appear back in your bank account.
Credit card payment? This takes the longest, up to 30 days to appear back in the card account used.
Why did the seller cancel the sale? Did you agree to it? If not, you can leave appropriate feedback showing your disappointment not to receive your paid for item.
