i've been trying to get them to honor a "high risk" cancellation for 2 months when i bought at 180.. they've resorted to stoping all communication. They said they would whitelist me but ignored my request for honoring it..
it took them 3 weeks to even respond.. JOKE of a company.
+1 same here. And yes you will have your purchase canceled. You can take goodbye from coinbase account since all your future transactions will be flagged as highrisk
