Come on vodacom get with it!!!

A few weeks ago I reported that I could not upgrade my son's mobile as there was technical error on my account stating I am in arrears. My son did contact the relevant department and they stated the system has to be reset. Nothing for 2 days ao I posted a review but had to do it twice before I was contacted by a consultant with a serious attitude. I informed him that it was to late to upgrade as my son was now on holiday in the UK. I did inform them however that even though we were assured that the system would be reset, it appears that it wasn't. Today I tried purchasing data as I sometimes do to top up but I get a message that my account is in arrears, really? So I post this on your website and I get an automated response blah, blah, blah. If I'm lucky someone might phone me back and assure me that all is well. On my statement it reflects my payment. Please try and rectify the situation for me. If I'm not the only one, you are losing out on revenue.
