OP was ignorant, and got tossed a lifeline. Also “just make everything zero dollars bro” is a ridiculous proposition.
This is a dumb analogy, but the point is there is very obviously a pattern in this payment process that is ripe for abuse. The question of whether or not you aim to be an abusive business, plucking every shady profit where you can put the onus on the customer to try to come get their money back is one that many companies are deciding, and many are erring in the direction of the dark pattern.
By not working to avoid this problem from the get go, there is an implication about how a company wants to make their profits.
I have no control over how much traffic my public sites get. There is zero value in me signing up for a service which charges me based on traffic if I can’t control the maximum they’ll charge me. Would you sign up for an infinite bill?
If it has always been a "policy" to forgive bills, shouldn't it have been 100% forgiven immediately after OP contacted support in the first place? Why go through the trouble of playing the hero by offering "discounts".
After this the CEO comes along and says that the policy is actually not to bill for this kind of event... But the company actually tried to bill this user 3 times... soo it all stinks really.
