Mchek deduction on tata docomo

Dear sir/Mam, I have a problem in my tata docomo sim. We encounter mcheck processing msg many time in a day during other work or calling to my relative or friend sir/Madam plz deactivate this mcheck processing msg as soon as possible in my no. 686. My name is mala singh. If this service does not stop within next 24 hrs, I will complaint to indian consumer court against tata docomo company. Thank you
