Unauthorized charges

I have three charges on my October bank statement from Google Playdemic that I did not charge or authorized and I would like a full refund for the charges and I would also like for Google Playdemic to block and,/or not allow any future charges to my account from my bank card. Please have someone contact me at cbkbfe@aol.com for information regarding dates and amounts of the transactions and where to refund them asap. Thank you, Carol B Kisling
