Vodafone India — cancellation of caller tune ([protected])

Address:

Bangalore, Karnataka, 560070

I have been asking for cancellation of caller tune for last 2 years. I have been calling customer care and also sending emails. On receipt of my request for cancellation of caller tune, it is cancelled but immediately there after it is installed without my consent. When i call customer care again they say that i have reinstated caller tune. But it is not true. Please cancel caller tune permanently without reinstating caller tune again. Pl. Refund all the caller tune charges
