Unprofessional

I called the customer service number (111) to find out what my charges a very help lady assisted me thank you. There was however 1 charge that I was not aware of upon cancelling/upgrading my contract. The agent didn't tell me about the BlackBerry Internet charge, nor did he ask me if I was still using a BlackBerry but I'm being, if the lady didn't ask me it would've carried on. I asked her to put me through to cancellation which she, where I could hear nothing so frustrating agents making a loud noise and scream in the background , sounded like some competition taking place. I had to called back about 3 times still with loud noise at the back, then 1 agent heard me but hung up because of the noise. I spoke to a Mandy which was kinda of helpful with an ATTITUDE . This is so frustrating and unprofessional I shouldve just cancelled the contract all together.
