If you are trying to submit your personal details but receive the error message "Invalid length or format" the form is having issues with the postcode or address. First, try to remove any spaces in the postcode field. If you still receive the same error double-check any symbols used in the address, for example, remove any apostrophes.
If you've received the error message "The value you provided for this field is already registered with another user" when trying to redeem your points for cash don't worry. This is a communication error causing your details to not be pulled up correctly by our system. Please log out and try logging back in after an hour. After this when you try to redeem again you should be taken to the bank details form.
We understand that this is frustrating and therefore we thank you for your understanding. Do write to us if you have any questions or encounter further issues.
