Vodafone India — unable to activate caller tune in [protected]

Address:

Bangalore, Karnataka, 560029

Hello

I am unable to activate caller tune in my vodafone number [protected]. When i am sending sms to 55655 or any other caller tune activation number i am getting below message from vodafone.

"we are unable to process your request right now. Any inconvenience caused is deeply regretted."

I called up customer care and spoke to many agents and there is no results and they barring my number in system. I have no proper support given from customer care and nearest vodafone store in koramangala as well.
Whenever i am calling customer care they saying backend team will contact you and they disconnect the call.

I am really fed up for a simple and single request to activate caller tune.

Regards
