Bad customer service

I am currently paying for an ups that isn’t working, their technician instead of assisting me offered to sell me another for R600. Yet I’m paying every month for the one I have. These people don’t care about customers all they want is money. I logged a ticket after loose airtime trying to call them. See their response below, my phone works perfectly.
