Vodacom staff very confused about services offered

Spoke with altogether six different people, called customer support twice, visited two shops. Can you unlock a phone that has been carrier locked. Received five different stories. No, we cannot. Yes, of course we can, but you have to take your phone to shop X. No, says customer services. We've not had a technician that can do that in nearly two years. Same with sim swop. Two different shops, two different stories. Done in three hours mam, says assistant at shop. That will never happen, says customer support. It takes 24 hours. Neither one right. Mum tries to do a sim-swop - I give her the information I have. I reckon I'll be right, cause I did it yesterday. Oh no. No, THIS particular shop works differently from the one I was at. Vodacom, maybe it would be greatly beneficial if your staff receive some training. You know, so they're all on the same page. All that's happening now is they give people the run-around. And people don't like that.
