Manager very rude

Yesterday 03/01/2019 I call Vodacom customer service as they have locked my data router. They are debiting my account to repayments. The account has never been in arrears. The consultant says they normally lock it because it’s behind, I ask for a manager to give me a better explanation as I was not able to carry on with my business since my internet was locked. As I ask her the question she just unlock the internet and hang up on me without giving any explanation, that I very rude and very bad service. I don’t appreciate that at all after being on the line for more than 10min waiting for a someone to assist. I do not appreciate your bad service, I even considered cancelling all my Vodacom lines
