itemised billing not dilvered

On the 24th of April I called at 6:11 requesting my itemised billing to be sent to me, I ws told I will get in 48 hrs and I never received. On the 30 of April I called again and till today I have not received my request. <br> Now I wanna know why must I pay for a service that does nothing for me? This doc is vital and I need it like on my first call already.....<br> <br> This is ridiculous and bad service,not to forget lying and misleading clients
