Yes I have already abandon my account two months ago, from when I am unable to access my coinbase account. After that I am start using multibit on my pc. But in this two month, on every few week, I am receiving email from coinbase You have just receive ........ BTC.Which makes me very sad.
Well, your funds are probably still in there. I think they just disabled your account due to inactivity or suspicion of hack attempts.
Since you've already reset your passwords, all you gotta do is let them know. (Reply to the email you got from them where they instructed you to reset your password instead of sending a new ticket/mail.This way they could take you to the next step. Sending them separate tickets/mails could lead to confusion, since they'll just think it's a new issue,so back to the end of the line. lol)
If still no response, then send another. Anyway, you just gotta be patient since they did get in touch with you before.
Patience, at least until you get your funds then of course, withdraw and use your desktop wallet from then on.
That way, you get to control your own wallet.
