Online Poker

I have just recieved an email from a major online poker company stating that I have won some money off a player and that money is now been transferred to my bank account. This player is claiming a chargeback, which basically means they are claiming that their card had been lost or stolen.
My problem?

States the issue has been reported to the police and the investigation team is doing a full investigation.
Might tell them I used it to pay my tax with good luck getting it back from that bloody lot

spam email? you wanna delete stuff that u dont know where it come from

I thought so....so I phoned them and the address its come from is a registed address from their company.
I've just emailed them back to an address I know is theirs with my mobile number obviously saying I will lick your bum and co-operate in the investigation, please phone me and tell me how I can help.
If they say send the money back I will try not to wet myself laughing but one can't make any promises

sound like a scum to me, i hope u haven't gave them any of your bank info

No and I didn't reply to them. I forwarded the email to an email address that I know belongs to the company. Just with my mobile number requesting they contact me. The first email has too much information already if it's not them. But im very intrested in how im ging t help their investigation.
"Did you win money off ths player playing online poker"
"Yes"
"Can we have it back?"
"In a bit"

yes sir i will gladly pay it back at 2p a month

Don't even no what player it is so can't even check my records to see how much I've won off them. Oh I so hope I have won somthing like 23p off them.
"You want 23p?..........course you can........just contact my solicitor with the court date"

Just an update I emailed them back and got nothing in return. Phoned them and the person has gone on holiday...great
Now for the bit im not happy about.....The mrs had £20 in her account said you might as well have it I never play poker anymore. So we transferred the money by playing poker against each other and she lost on purpose. Happened over 2 hands. This company has now only shut my account and wants ID and full explanation and told me there is a good chance that they will shut my account and keep the money lol.
Only won a few grand so I think there might be 2 court cases coming up if they think they can just do that without a fight
Why I ever opened an account with these i'll never know
