I never had an issue with withdrawals or anything else with them. Surveys pay out, apps pay out, no problems there. I'm thinking that they are very selective in what they respond to and have little ability to help your situation.
For example, I think somebody logged into my account and set up 2FA. So now even though I can still access CP via the faucet sites, I can't do anything with my balance, nor disable 2FA. After emailing them multiple times with no response within the 48 hours, I created a new account and set up 2FA myself (one that's actually linked to my phone). Theres a message in the setup that I need to record my secret key because CP won't be able to reset this (I forget the exact wording..)
I think that I would get a confirmation email upon withdrawal to confirm, so that should stop whoever broke into my acct from successfully withdrawing the coins. However, that doesnt do me much good either since now the coins are stuck with CP!
Man, I just wish they would just communicate with me and at least offer to force a withdrawal to the same BTC address that I had been withdrawing to since CP began!
