Scam.

customer support replies the following.
"Your account is blocked because of the rapid growth experienced in your account which is not suitable for the package you currently run. An upgrade to a higher package will be required on your account and this will cost $1,299 to perform. "

Showing you have more funds to lose, they tempt you to extract more money from you.

They won't agree to take this fee from my account (which has more than the fee they need), they just say that the account is blocked
