As an incentive for legacy customers to promote Public Mobile and recruit customers, I think legacy customers moving to any pick and pay plan should be eligible to the Refer-a-Friend rewards "earned" by refering friends (who are still Public Mobile non-legacy customers) while they were on a legacy plan.
(more details here: http://productioncommunity.publicmobile.ca/t5/Rewards/Refer-a-Friend-Reward/m-p/144382 )
I understand that the Refer-a-Friend reward cannot be applied to legacy plans, that are already cheap and a good deal. But why not making it retroactive (like the loyalty reward) as:
1) an incentive to talk about PM to friends/promote PM/recruit customers, and
2) an incentive to eventually change from legacy plan to current plan, which is what PM wants anyways as we have seen with the $3 increase/switch-to-Koodo "promo".
