Disappointed in vox's lack of communication

It has been a week that I logged my problem that my UPS does not charge. A week that I am losing work time during loadshedding. I tried phoning Vox numerous times this week, but the queue is so long that it took my R30 airtime and I still was in line. I cannot afford R200 airtime just to be able to speak with someone. I tried emailing numerous times, but no one gets back to me at all!!!!!!! I cannot believe this service I'm getting from them. No one is getting back to me in any way and here I am still waiting for them. Terrible.
