[Resolved]  Reliance / Big TV — Sales promotional SMS

The company got my cell no. from some source and have started sending a large no. of sales promotional sms's any time. I am a responsible official (General Manager) in a large company. I have to conduct meetings and attend to cell phone calls. I had rang up Big TV call centre requesting them to stop these SMS's but they bluntly declined my request. I contacted my cell phone connection provider Vodaphone but they said that they cannot block these messages.
Request your immediate help.
