Worst service ever

2 years ago I had an incident with Vodacom where someone at Vodacom **********ly upgraded my account. The same day as it happened I tried to correct it. They said it was a glitch in the system. Then I had to get another number for 3 months while they try to see who it was. With NO correspondence. I had to phone every time I needed an update. When they got it finally reversed after many calls and airtime wasted, and I haven't even used my number, and poor service, I ported my number to CellC. After a year they phoned me for a bill apparently not paid and I referred them to the ***** department. The bill was corrected. After 2 years now they blacklisted me for not paying my account at Vodacom. I'm not even with Vodacom. No one ever let me know that there is an amount outstanding or why. I don't have a Vodacom number now for 2 years. As I am trying to resolve the blacklisted matter now in July someone phoned me for a settlement. R250/month. It's ok, I want to clear my name in the meantime so I'll pay it so long. Today 5 Aug they phoned me just to say my debit order is behind since March. ***!!!!!
