POOR SERVICE

good day, I have contacted Vodacom 082 111 5 times today and each time received different information for the same enquiry which is unacceptable. All I want is a itemized billing for one of my numbers ***. firstly I was told it would cost me R30 once off then when I asked for it the lady couldn't pick it up, the next consultant told me its 22.50 a page for once off as I am not linked to itemized billing then again the following one told me I could request it for once of R22.50 however they need my copy of my ID, Why should I send a copy of my ID when they do telephonic verification.The other one told me to register online then I will receive it and online you only see your statement no itemized billing.
