Vodacom is *************!

I have had a Vodacom account for as long as I can remember. I have not had itemised billing and never knew that it has to be specified. I now need to prove that a call was placed in September 2023 and requested an itemised bill for that particular month. I am prepared to pay for it. The Vodacom branch at Cape Gate could not provide it. They phoned customer care who told me that it can be furnished in 48 to 72 hours. They kept me on the line for very long time before I was provided with this answer. I now receive a sms saying it is no longer possible and the query is closed! Why? It is my personal information? I phoned from a branch providing all my “security information”. This is shocking service provided by the uninformed! After 20 years this may be the reason to find another provider.
