Vodacom get your act together.

Will the harrassment never end? Vodacom...well I have Vodacom "service" on my phone. I buy airtime and that is it. Some months ago in another town I ordered fibre but cancelled it when I left the place I was living in because the landlord died and I had to move. Someone came and took the equipment away, I paid what I had to pay and that was that. Yes well... NOW....months later I get a call from a debt collection agency saying I owe Vodacom R1000+ For what? The agency wants a certified copy of my ID and some sort of proof (how can I prove I DIDN'T do anything?). I have Vodacom pay as you go on my phone and that's it. I HAVE NO CONTRACT WITH VODACOM! I am an invalid living far from where I was before and can't get out to have my signature certified and my validated and send it to VVM. What's up with this country? Every time I but anything I get cheated, overcharged or harrassed. Telkom, Cell C, .....yada, yada...I'm scared to go out, which is just as well because I can't anymore. So? Vodacom?
