Slow to refund

On 22 July I ordered a Canon EOS RP battery back. The money was deducted and order confirmed. On 2 August I sent an email to enquire about the progress of my order. Only on 5 August was I told the refund would take 10-14 days, after I enquired. On 10 August I enquired if my refund has already been processed. On 11 August I was told it would take 10-14 days and they would check if their accounts department had processed my refund.

How does no one know when my refund will be processed. Why does it take 10 - 14 days to process a refund?

Their customer service is pathetic.
