The rule is the same for all Bell returns (Express Vu, Mobility, Sympatico, Telephone) all over Canada. When they send you a refurbish unit to replace a broken one yu have 30 days rom the day you receive it to ship the old unit
The only 10 das rule that exist at Bell Express Vu is when you originally suscribe. You have a 10 das period during which you can cancel whithout penalty. After that 10 days if you cancel you will have early termination charges
