Vodacom frustration

I cannot receive any calls since returning to SA on Saturday. Can make calls no problem. Tried twice via online chat to sort the issue they were unable to assist. Phone 082 135 and was on for 59 minutes where the supervisor by the name of Cindy decided to rather cut me off and transfer me to rating the service. Thabo tried to assist, but this is a bit above his pay grade I would assume. Best of all is I have not used any calling or answering whilst out of SA as Vodacom would like to take over my inheritance for every call I make or receive while out of SA. I did send 2 sms's, and accept those costs. Vodacom decided they have not ****** enough, so they are billing all calls I now make since Saturday back in SA at Roaming rates. Well done. I am now sitting with the most expensive contract conceivable that cannot even accept incoming calls. They even offer to phone me back when they find out how to fix it. Really funny as I TOLD you it does not receive any calls.
