RUDE CUSTOMER SERVICE

I just received a message from SABC to say my licence is in arrears to the tune of R265 which I assume is payment for the current year. I called them twice to try and understand the meaning of " arrears" , and to also ask if, as an old aged pensioner I'm not eligible for a discount. On both occasions they would just drop the call which is a waste of my money and airtime. This is rude, cruel and unprofessional!! I need them to call me so I can ask the questions and get the clarity I need and deserve.
