That's interesting. I checked out the section of the terms that they are referring to.
7. You are only permitted to enter Free Bingo for your own personal entertainment and non-professional use. Any other use of the Free Bingo games
is strictly prohibited.
8. Constant use of the free bingo rooms (i.e. playing free bingo games more than 3 hours a day on average every week or staying in the free bingo rooms for more than 120 games per week) will be regarded as professional use.
9. The Company reserves the right to block or remove a player who violates or fails to adhere to these terms and conditions without prior warning.
The max withdrawal from the free bingo rooms is £100 for non-funded players. Even if you haven't requested a withdrawal, you certainly could. This would be why they lay out clear limitations of use in their terms & conditions.
I'm sure you meant well magicmitch and are just enjoying a bit of online bingo. Yet another reason why we have to read those darn t's & c's so closely. Ugh! Not to fear though, there're plenty of good site out there.
