I've been charged twice for the same subscription! This is ridiculous.

14:22

I'm sorry to hear about the double charge, Marcus. Let me look into your account right away to resolve this.

14:22

MC

I want a full refund. This has happened before and I'm losing patience.

14:23

I understand your frustration. I can see the duplicate charge of $29.99. Let me escalate this to ensure a quick resolution. ⚠️ Escalating to human operator...

14:23

Hi Marcus, I'm Alex from the support team. I've already initiated a refund for the duplicate charge. You should see it within 2-3 business days.

AI Co-Pilot Suggestion

"As a goodwill gesture, I'd like to offer you a 10% discount on your next renewal. Would that work for you, Marcus?"
