Vodafone India — activation of services without my knowledge

Good day, i've bought a new phone and vodafone sim card in may, 2017. Problem started on 24th of july. There were some services which were activated in my phone without my knowledge and my balance was deducted. I never requested for any such services (Game pack, mmovies pack to name a few). I called vodafone customer care executive and they told me that they'll resolve the issue, and they did. The very next day above mentioned services were again activated. I called customer care and they solved it. This happened for 3 times. From 26th july onwards i couldn't even connect with the customer care executive so that i can get my balance back and cancel all these services. Please help me resolve this issue. Otherwise i'm thinking to port my number. Thanking you..!
