No wonder allbthe branches are closing

I had a contract with Nashua which moved over to Autopage. 2 GB and 100 minutes and smse for 24 months at R400. Went well till they switched to Autopage. Now I get called for an upgrade and a week having the phone the mic doesn't work and I refuse to book it in for a service 6 weeks as its my work phone and the consultant who sold it to me refuses to help when I go to Roodepoort branch. The upgrade was a M4 aqua and sony watch and 50 minutes and 1GB day time and 1 GB night time. I used under 650 MB last month and got billed extra R50 now we are at the 7th and My data shows its up 0 GB left and my bill on R14 extra already but I've only used 247MB. I was told I will get called by a manager as they are always in meetings... 2 weeks later I am still waiting as the phone is broken in the first week and I'm getting charged extra when I've yet to use my contract data. Call me asap or I will reverse payment till I get what was agreed to.
