Refund my money

I bought a fan online a month ago it was faulty that I had to return it and it’s been 3 weeks since I have been promised a refund This is the response I get every time I follow up:

We are actively working to resolve the current issue as swiftly as possible. We sincerely apologize for any inconvenience this may have caused. Thank you for your patience and understanding.

I m not even understanding I just want my money back.
