Unable to provide me with an itemised billing statement

Yesterday I called the Vodacom call centre requesting an itemized billing statement this after logging on and checking on Vodacom online. The call centre could not assist me and requested me to go to a Vodacom store. I then went to the 4u store in Sandton and they again said they unable to assist me and that I should call ********** , I called later and yet again they asked me visit my nearest Vodacom store...I then went to the Vodacom store at Cresta and guess what again they could help me , called the number again and surprise surprise i got asked to visit the nearest Vodacom shop.This is pathetic service really , how difficult can it be to provide a customer with an itemised billing report even after itentifying myself with my ID at the stores.The functionality is also not available on the online portal , what is happening here really...
