Have never received feedback and manager hangs up

I am highly disgusted with the service that I have received.<br> A few months ago I had a problem that my 3G worked but my line was still soft locked. It eventually got to a point where they had to remove my soft lock and then had to adjust it to R450. Point made is that Vodacom said that I just need to phone in and they will put it back to R50 as my permanent limit that it always was from the start. Now the *********** staff said that they can't and that they have to first escalate this and get back to me. Even the manager put the phone down and put me through to the rating them automation after I asked to be put through to someone that could help he. Every single time they have NEVER got back to me - even about my last query about my account resetting to the wrong default. So yes I get scared when they say that they will escalate it as to date I have never received ANY feedback about any and all of my queries that have been escalated. I am disgusted about the way the last manager who I was put through to just put the phone down. No point of phoning 082111 if they can't help me. It had been confirmed again and again by Vodacom that I just need to phone in and ask - clearly a lie.
