On the 2nd day, i was billed 99.00 but no explanation. the account said i was low on credits. I cancelled the account with their automated since it's impossible to reach customer service. Next day, more emails and billed another 99.00. i tried to cancel again and even deleted my account. Next day, more emails in the inbox. I cancelled once again, and deleted my account again and wrote them a long note telling them they are cut off as i advised my bank not to pay this service. today i have more emails.
Recommendation: Don't sign up...
