I wouldn't expect them to drop the company as a client; I don't think that really serves anyone.
My suggestion would be to levy higher transaction fees on the business, and provide refunds to customers out of that. If a company is going to ban users for filing chargebacks, raise their transaction fees by 0.5% or 1% and have the CC company issue refunds themselves out of that pool.
At the end of the day, it's really a problem for the government to solve, though. Companies being able to get away with such blatantly anti-consumer policies is indicative of a substantial distortion in the market. I don't think this is something that would happen if there were robust competition in the market.
