HELP: Adobe + DropBox billed me wrong

Its intriguing to have found out on the internet just how large the number of people is who have been scammed out of their hard earned money, in the past year, without knowledge even, due to DropBox’s egregious disregard for client safety & irresponsible handling of client billing/bank info.   No phone number, no email, no customer service, no help, just the run around.  There is only one reason for these tactics & its to take people’s money.  They have created this loophole and chosen not to have ANY customer service to assist the people paying for service.  Last I checked, even though I dont have a single account, it was MY bank account bejng charged over 29 times at $11.99 & $12.99 each, by about 20 or so random people, so, I AM a paying customer.  A data breach, or a hack to the system?  No, this comes from the inside.  In 3 weekly rounds of debits, my bank info was assigned to roughly 20 DropBox customers, BY DROP BOX.  Whether these clients know, or dont know, is not my concern because the thing they all have in common is DropBox.  These debits were clearly generated from some sort of automated billing list.  DropBox has yet to reach out to me regarding this egeregious mishap on their part.  I have accessed all of the transactions & know the user names.  DropBox has forced me to pay over $300 to DropBox for these 20 or so clients, possibly because they were also initially billed improperly (?) & now DropBox is playing pass the buck, trying to take people’s money,  no matter what the means, is that what?  Im contacting my attorney.
