Vodafone India — disturbance calls

Address:

East Godavari, Andhra Pradesh

I am a customer of Vodafone (migrated from Hutch). But whereas we are receiving frequently unsolicited calls disturbing us very much. The timing is such that when I am in Hospital, we receive the call. When we are in meeting with the Bank Manager, we receive the call. When we are discussing with the Doctor, we receive the call. Once I lifted the phone to find out what is the content of the call, to my surprise it is a call related to the selection of caller tunes from among Ten tunes. Should we have to bear this nuisance for ever.
I found even my neighbours too receiving such calls. They are aged about 80 years.
The phone call list I enclosed herewith. Kindly advise. The phone no is [protected] etc.etc.
