I opened a colt account to play at the ofc last month.
I had rake back on the account. After the ofc was over, they sent an email saying my account was suspended because i had rake back on another cake network account. I email colt and they said that i could open a new account without rake back. I tried to do that and there as difficulty with getting the account set up. Eventually it was set up and the balance at colt and power were transferred. Also the rewards (except for the rake back) were transferred too.
there was a total of over 30 emails by the time every thing was done. almost all were done on the same date and the longest wait for a reply was under 1/2 hour.
it was a pain in the ass, but the customer service was well above what i expect from a poker site
