Idea Prepaid Connection — Not able to deactivate Service Calls

Hi All,

I am really very disturbed with all the unnecessary service calls I get on my Idea pre-paid number. I get atleat 6-7 calls daily along with 4-5 messages. I never activated these services. Customer should not get disturbed unnecessarily with all these services, if they don't require them. Please let me know if someone knows how to deactivate them. My number is on roaming from last one month and my incoming calls are even paid on raoming. I am really disturbed with these calls and sometimes I miss important calls even by not picking up with a confusion of getting service call from Idea's end. Kindly Help!
