Tata docomo activated miss riya service

Around 012, tata docomo charged me rs. 23 for a vas service "miss riya", which I never had requested/Activated. I tried to stop the service using *191# but I am unable to do the same (it shows no services activated). On 012, similar deduction of rs. 30 was done stating "hi!subscription to miss riya has been renewed". Please help! I cant disable/Stop it either. I don't want to loose my money like this. And the customer care representative just said, sorry we cant do anything right now, it is a bug in our systems and we are trying to have it rectified asap. Now, who the hell will return my money and assure no more activations of unwanted paid services?!
