Thanks thanks thanks so much! You all have given me much of the information I needed, and have been a real comfort. 

Hi there,

I've posted on every other medium I could find about my frustrating problem, but I've received no response, solution, or support whatsoever from Coinbase.  I'm starting to post on Bitcoin forums on the off chance that someone from Coinbase (or someone who has knowledge of their system) could help me.

On October 21st, I opened a Level 1 account with Coinbase and purchased 1BTC. The very next day, my checking account was debited the $184.14 the BTC was worth. My coin was due to come in on Friday the 25th.

On Friday, my transaction was cancelled due to a "high-risk" transaction. What I've gathered that to mean is that Coinbase's automated system calculated my account as being possibly fraudulent. Yet, how COULD it be fraudulent if Coinbase already debited my account?

Like I said, I've gotten zero answers about my problem, zero responses from the website. I've posted on Coinbase Support, sent a private support e-mail, and I've written about my problem on Twitter, Reddit, and other forums. As of right now, Coinbase's silence has me convinced that they've stolen my money.

CAN ANYONE HELP, THANKS.
