Good, and as expected.
This is completely normal for companies to do this and there is a 99% chance that doing a chargeback will get your account immediately terminated.
You cannot have it both ways with chargebacks and keeping your account as I have said before [0] as it is rife with abuse and friendly fraud and the merchant reserves the right to suspend, terminate and ban your account if you do so as per their ToS.
So this is of course hardly a surprise here.
