Charged twice for one account

I signed up for a basic dropbox account in January 2023 and paid for the yearly subscription. 

I then noticed that I was charged another £80 for the year in March 2023 again. 

When I tried to speak to a member of customer service about a refund for the second charge, I could only get through to a robot which didn't solve the issue at all. They then transferred me over to an email conversation where I thought I could speak to a real person, yet it was still a robot.

The bot then cancelled my original yearly subscription (already paid for) when I clearly said that I just wanted a refund of the second payment taken by Dropbox and DID NOT want to cancel my subscription. I heard nothing more and couldn't get through to anyone else. It's literally daylight robbery. 

The whole thing just seems like a ploy to steal off people and hope they don't notice. Then when they do notice, there is no actual way to speak to anyone to resolve the issue, therefore you can't get your money back. Not only have I been charged twice for something that I didn't buy, I have had my original subscription cancelled that I paid for for the year and it has caused me numerous issues with not being able to use it at work etc. 

When I looked up again how I can request a phone call from a human member of customer service at Dropbox, it said it was only possible via purchasing the premium level of dropbox. This is ridiculous as the customer has no actual way of resolving the issue. 

Has anyone else has issues like this?

Really disappointed that such a giant mainstream company can deliver such poor and questionable customer services and actions. 

If anyone has the number for a human at dropbox, I'd like to speak to someone to solve this as I am owed £80 and I want my original subscription to be renewed as it is already paid for for the year. 

Thanks in advance.
