Idea Cellular — Mydala deduction

29 rs has been deducted illegally from my talk time account by idea in the name if mydala service. When enquired in terms customer service they are repeating the same dialogue. How would I subscribe to something even I don't know.. Why should I pay money for something like that. They are not even bothered about the customers. It's like looting from the customers. Till now I have used idea services. Now it's charging money illegally too.. Better port my number. This will continue and we can't say anything and the executives always talk like it's our fault.
