Fraudulent Payment

In May and June 2020 I had four separate payments, totalling CA$267.26 made to my Credit Card for Adobe purchases, all of them fraudulent as I have no Adobe account.  I queried the payment with my bank and they told me to contact Adobe.  I contacted Adobe in July who agreed that the payments were fraudulent as the name, address and email attached to the payments did not correspond with mine.  They gave me a case number, ADB13957979T1K3 and told me that these amounts would be credited to my credit card.  It is now October and I still have not received the money.  I spoke to an Adobe accounts agent again who told me that I needed to ask the bank to investigate and return the money.  This I did, but my bank only investigates 120 days back, so now that it is over 120 days, they can't do anything.  I have been back to the Adobe support agent, but told there is nothing that can be done. I was not told to contact my bank in July 2020 when I first reported the incident to Adobe, I was told it would be returned to my credit card. So as I see it, Adobe conveniently gets to keep the CA$267.26.  There must be some alternative way that this can be resolved, with some justice done in this case. Please can you advise?
