WORST CUSTOMER SERVICE EVER

Apparently I owe this company money after canceling a contract YEARS ago. I was not made aware in ANY way that I owe this company and now that I'm trying to figure out what the **** is going on, I have to deal with a ****ing robot. So arrears on my ID number can be picked up from their sales department but according to TOBI, their fvcking robot, its either invalid or cant be picked up!!!!!!!!!!! What in the actual fvck Vodacom? We are good enough to deal with humans when you want to sell us something but not when we need to resolve an issue? Why? so that you can keep getting more and more money from us?
