I have a simple solution for this kind of problem: -

Take your money elsewhere.

If you are having problems already, better you know now, rather than later when your business is really dependent on an entity like this behaving in a proper commercial manner.

Some companies I refuse to deal with because of the way they have behaved towards me in the past: PayPal, NAB, Telstra, Amex.

Those companies have missed out on literally decades of income from me due to their smart-ass ways.
