Fido monthly credit + loyalty plan?

Hi, wondering if anyone has any experience changing their market plan to loyalty plan offered in your account. Will existing bonus data and monthly credit be removed? Currently have two monthly credit, one is $10 off for 24 months, another $10 off for 12 months. Chatted with their customer service agent online, the agent said the bonus data will be removed but is unsure of the credit and baiscally said "try at your own risk".
