This can be avoided by simply looking at your line stats before making the request. If your line, without any changes, can support 5Mbps without issues, then there's no risk of fee.
warning that Bell will charge $75 for diagnostic on the profile if they rule that it cannot be changed to 5Mbps profile then I would have to pay $70. Immediately I request my account to be cancelled.
