I do worse (I'm bad, I know). A large Telco in Australia once charged me $800 in phone calls several years ago before the TIO and ACCC mandated SMS notifications when accounts go over a certain amount.

I explained the situation to them, that I was a good customer, I'd just had my first child, could they shave off some of the bill as a goodwill gesture. Even $40. They didn't budge an inch.

Over the next 6 years I've made a complaint about every single fault, bill error, outage and mistake they have made. Each time I've demanded compensation. I have a number of accounts with this Telco.

I estimate that I've recovered $700 worth of compensation. I'll keep going till I get the entire amount back, then probably go on for another $100. Then I'll stop. And probably find alternative services and dump them completely.

Don't piss off your customers.
