We have a relatively large spend ($5k+) @ DO, for a unique client (most of our other clients can be served by our colocated facility), and I'm going to second this. Or with any other provider. They should always explain exactly which rule was broken. If the customer is legit + genuine, they will promptly fix the issue and won't be a further problem. Being vague makes it super troublesome to rely on any service that takes that tactic. (Like Google, for example) If they continue to re-offend, and find other ways to skirt the rules, that's when you move on to account termination.
