I was charged 6 times more money for a marketing call to my cell phone. I have been charged 4 times more money for incoming calls to my cell phone. I think once I was charged for a wrong number (do not remember correctly) to my cell phone. I have been charged many times more money on 5 or 6 occasions. So everybody please check your cell/mobile phone bills to see whether you are charged correct amount. I am using a pre-paid service for my cell phone.
