Account Query Handled Badly

To sum it all up, my Vodacom contract account was removed from the network. It is only two months in arrears and I made the necessary arrangements with the consultant that called me to avoid this rather unpleasant action. When I try calling the call center, I spoke to Petronella Mathobela who assured me the Line Manager would call be back on 17 June 2015.I waited for the call all day and no one called. On 18 June I tried calling the call center again but couldn't get through. At 8:47, I spoke to a very rude lady, shocking that she even deals with customers. She refused to give me her full names and only told me that her name is Madeleine. I'm very frustrated with this treatment from Vodacom after having this contract number for the past 11 years. They won't even let me speak to the line manager!
