Tata Docomo — unnecessarily VAS deduction

Address:

West Medinipur, West Bengal

sir/madam
my self tathagat som, i am using TATA DOCOMO mobile service, my mobile no is [protected]. On 25 july 2012 I talked to custumer care of tata docomo to deactivate my VAS service magic sms and he insures me that he has done but after some time I got massage that I have requested some other VAS service (mitti ke rang) on my mobile and on 29 July when I recharge my mobile with Rs. 300 then after nearly 8 different VAS services activated on my mobile without and request and deducted around Rs 210. When I talked to customer care they told me that I have request all these services one by one through sms but in fact I didn't. After a long argument they agree to refund Rs 140 and deactivate all these nonsense services.
Now I want to know that if I have requested for all these services then why they refunded my Rs 140 and Please help me get back whole money that have been deducted.

thanks & regards
