Vasan eye care - Dharmapuri.
I have went for an eye checkup and ordered a contact lens, also paid ₹1500 in advance for it. I'm trying to reach out to the hospital for more than a week. But they are not answering my call. You should take an immediate action or just repay my amount. I'll check for a better hospital than this.
