Request an exception is a form only available to higher payment tiers.
The primary method to increase tier and model limit is to follow the instructions of how much to prepay.
Changing tiers after a payment finally ages enough takes ANOTHER payment for recalculation. If you paid in that $101, and waited a month, it seems nothing’s going to happen until you place at least another minimum $5 into your account.
This topic originates from before tiers and automated increases.
