Vodacom is quick to judge

yesterday I went to Vodacom to take a contract and I was told that im on the system as pre legal on my previous contract, the guys at the store couldn't give me a reason why and told me to go to the customer care centre then I went to the cust care centre and they also couldn't give me a reason why they have put me on pre legal, i don't understand how they can put me on pre legal when they have debited my account every month and i paid it till the end of term, now they blocked me,i will sue Vodacom for this and i will put it in the papers and every social media about what Vodacom is doing to their dedicated customers and i will make sure that nobody takes contracts with Vodacom and i will make everyone change their network over to mtn or cellc cause Vodacom will make their name bad and im sure no1 wants a bad name,if i don't get a response back from this i will proceeding with my complaints to the papers and social media
