Hello MK03,
Welcome to the community!
While I am not certain of the exact number of attempts prior to the charge, I do believe that they do still charge a Returned Payment/Cheque Charge (see here).
You should note these forums are community-driven and not intended as a venue for customer services. If you would like verify the number of attempts prior to receiving the fee, you would need to contact customer service. In addition, they can also be contacted via Live Chat, Facebook, or Twitter. Those methods can be accessed via the contact page posted above.
Hope this helps 😀
Cheers
