vodacom bad service

i bought a sim card to do an online sim swap, failed the questions, they then advise me to go a branch. i go to the greenstone branch. they ask me the same question i was asked online, doing the same thing expecting different results. i failed the question. the guy advised he cannot do the sim swap and i wont be able to retrieve my number. Why did the send me to go to a branch when they knew the branch cant help me as well, not only did they waste my time, they wasted my petrol… the guy says my account was handed over to legal because on non-payment…and he showed me on the computer screen. i have never missed a payment and i close that contract a while ago

vodacom is loosing me as a customer and their service sucks
