Vodacom Call center agent STINKING ATTITUDE

I have a home internet contract with Vodacom since 2023. I have not received an invoice or statement since but the debit order keeps going through. So that is not my main issue. My issue is, the router started giving problems last week so I ask my brother who stays where the router is stationed to contact Vodacom. The lady who answer at customer care gives him a bad attitude and tone because he is not the account holder. The same lady contacts me and asks security questions, I could not answer some of them especially the account number and package type because I do not have any invoice from Vodacom.When I explain that to her she then gives ME a bad attitude. She asks me why I did not follow up when I realise I did not receive invoices. I again explained that I an too busy and expect Vodacom to do their part when I request invoices to be mailed. She goes on and on asking me again basically telling me it's my responsibility to do follow ups. So I asked if she then can't help me and she said "No, go to a Vodacom shop to get help". I know there's protocols and procedures in any organization but is Vodacom telling me they cannot assist me in anyway if I cannot visit the physical store? AND THE STINKING ATTITUDE THAT THIS LADY GAVE ME when it is actually Vodacom the did not send correspondences. I WILL NOT STAND FOR THE ATTITUDE, AS A CUSTOMER I EXPECT BETTER!!!!! SHE IS RUDE. I did not get her name but she called from this line +*** at 10:59am today 02 May 2024.
