BSNL Mobile connection — Service Activate without permission

Address:

Ambala, Haryana

Hi,

In my phone i received one message on 27th June 2013 at (6:56 pm) that service is activated on your mobile. I called to customer care (7:29pm on 27th 2013), executive told me that they don't have such record of activation of that service so call us later and when next day I call again for the same they told me that 'Ki apko kal call karni chahiye thi ab hum refund nhi kar sakte' and they also told me that their are two more services activated on my mobile from last December but I haven't activate any service.
So please have a look because I don't know how many customer are bluffed and have to suffer from the same problem.
