Unacceptable Service Delivery by Vodacom!

I am sick and tired of Vodacom! They have no administration skills nor do they ever have their house in order. I was recently contacted by their attorneys stating that my account is in arrears when I have already cancelled my contract over a year ago! They took a ridiculously long time to connect our fiber and it was connected for not even 3 months before I requested to cancel the contract as we were relocating. I was informed that I had successfully cancelled my account and therefore relocated, however now I get contacted saying that my account is not cancelled and in arrears! Vodacom really needs to get their house in order and improve their administration as it is absolutely atrocious! I would never recommend their services to anybody! Seriously ***********!
