I'm trying to resolve a billing issue and I can't reach support.

I’m disappointed to have to post here, but I was directed by Dropbox to “lodge a complaint” in this forum. 

To give you some context, I’m trying to address a charge on my credit card that Dropbox processed without my authorization. Initially, I followed the link from my banking app to report this issue, but I encountered an error stating that I hadn't entered the last four digits of my credit card, despite checking everything repeatedly.

I then used the chat support and spoke with John in sales, who told me I would need to submit a request to billing, which requires an email address linked to the account. The issue is, I don't have access to that email. 

When I asked if there was a phone number I could call to resolve this, John’s suggestion was I pay for a subscription to Dropbox so I could access customer support. It seems pretty ironic to have to pay for a service to resolve a charge for something I didn’t even want in the first place.

After asking several times how to formally lodge a complaint, I found myself directed here, where I suspect I might not see any accountability or resolution. It is very disappointing to see the lack of customer service and poor complaints process
