It is horrifying and it should be illegal to provide so little customer service when you encourage deep, irreplaceable investments into your platform.

Having thought about this some more, I really can't recommend doing a chargeback with any company you want to keep taking your money. Afaiu this doesn't cancel the contract, so you owe them the money unless you manage to void the contract, in which case they should send the money back anyways. Then, teaching all the fraud detection systems that your exact usage pattern leads to fraud seems unpleasant too. Just too many ways for this to backfire, even if the company doesn't play offended.
