We downgraded out plan for the winter (at the reps recommendation and not the unlimited plan). We confirmed multiple times that it would be no problem returning to our original plan.
In the spring when we called up to reinstate our original plan, they said yes they have the note the rep added from when we originally changed the plan in thier records but it didn't matter because thier rep was wrong. After 2 months, we finally sorted it when they came out with a new plan that was equivilent and they applied it retroactively.
It's insane how they operate.
