Poor service

Every day when I buy voice bundle at Vodacom it doesn’t activate. I will have to borrow voice bundle from them that comes with interest and I will have to borrow data bundles that also comes with a huge amount of interest because If I buy from the bank it doesn’t activate. If I buy from the bank I need to post here to get their attention so they can activate them because they call center is always refusing to assist regarding this. Even when they respond they take 5 days to resolve such a small issue and they refuse to reverse unnecessary transaction that took place because of they fault. Now because this has been an ongoing issue I need to involve ombudsman in order for them to respect me as their customer
