Idea Cellular — Caller tune subscription

I eas charged for caller tune subscribtion many times. I promise I did not even try to subscribe caller tunes. It was not single time I was charged multiple times. How can you subscribe caller tune without my concern. For this reason only I want to change my service provider. Please and consider it as serious complaint. I don't want any subscriptions from your end. Never ever change me again for these caller tunes. I have sent STOP message to your subscription but never helped. And If it repeats for other time I will definitely change to other provider. I wish for refund if possible. Because I was not charged single time to neglect. My hard earned money. Please refund
