Every month same billing problem with Vodacom

Every month am having the same problem of ordering my itemised bill online and being charged but the itemised bill never gets delivered to my inbox. If you check your records you will see that this time last month i made exactly the same complaint until someone from prepaid services emailed me the statement. Vodacom please help .This is very frustrating and you are really testing my patience!!!! This is unacceptable. I am wasting so much time following up on you and holding on to get help but no one is helping. This is really ****y service!!First time i would understand but second time is now pathetic. I promise you if this is not sorted i am moving from you!!!
