Bet365 Mail Delivery Problems

Hi, I just finished the initial 250 raked hands at Bet365 and when I try to send them an email to claim the bonus, I get this message...

"The following addresses had delivery problems:

<support@customerservices365.com>
Permanent Failure: Other address status"

I have never had any problems with my email account before yet an email sent last night as well as one this morning were both returned with this message. Anyone know of a working email address from bet365 that I can use to request this bonus?
