Money taken by UK hotel after cancelled booking - any advice?

Discoqueen18

Hi there
I recently cancelled a booking for an hotel in Northampton due to covid. This was made via booking.com and cancelled free of charge several days before the date I was due to go.
Booking.com then sent me email confirmation of this free cancellation.
On checking my visa card a week after I was due to go I noticed the hotel had charged me TWICE on the day I cancelled the booking.
I called the hotel and Booking.com and after providing evidence of my bank statement, between them, I am not getting any answers (in fact the hotel has been quite rude to me in the last few days).
I am now in debit on my credit card incurring charges that again the hotel and Booking.com do not seem to understand.
Can anyone offer me any advice has to how to get the money back that shouldn't have been taken in the first place? 
Much appreciated.

Contact your credit card for a chargeback.

Contact your bank and chargeback as zx81 said.

When you contacting booking.com/the hotel did you show a photo of the bank statement or did you just tell them the issue?
I would show a photo of the statement if you haven't already (although I am sure you have)

Thanks everyone. I did supply both parties with a copy of my bank statement heatherw_01.
The hotel keeps now fobbing me off, telling me to ring at a certain time but today was quite rude to me saying they were not available to deal with this problem. I would be nice if they apologised and/or acknowledged my emails. I am trying to help (with their error) and move the process on. 
Booking.com keep telling me they are here to help but aren't actually chasing their "partner" as I have requested.
Now they have sent an email to say it could be up to 15 days before I get the refund back.
So I'm back round going round in circles with me doing all the work for something that isn't my fault.

Being at work I can't get to the bank till Saturday as they close at 3pm
I was nearly in tears today after the last conversation with the hotel as I feel so at a loss.
Being in the public sector £100 is a lot of money. 

Trying to remain calm but I have to say its really getting me down
Thanks again for any help or advice

You don't need to get to the bank. Call your card provider or contact them online.

You were right about speaking to my credit card provider, they have been great and really reassured me.
Thanks again for listening and your advice
