Bad customer service

My husband and I have been married now for 22 beautiful years and that is how long (if not longer) we have been customers of Vodacom. Due to convenience, we just added my number to his contact, then my mom's, then my son's, as we all in the same house and it goes off as one account. Problem is my husband has given written authority that vodacom cN speak to me as he is not always available and I am now working full time from home. But each time same story about security. I know all the answers, but it must be a man's voice grrr. I am so fed up with vodacom and all their telly sales people and excuses. At the end of the day, we have 4x phones, pay our account, but really tired of bad service
