Disappointed with DSTV.

I was recently due to pay R120 towards my DSTV account on the 30th April. However, I decided to make a payment of R400 instead of R120. So I was expecting to have channels added or to at least have a credit on the account since I paid more then the expected amount. I paid on time but my services are disconnected and i cant view my channels. my concern is who will be liable to pay the reconnection fees because my account is disconnected falsely. I am at work everyday and the last thing i wanna do is constantly be calling their unprofessional customer care.

Please help me! i want a refund or my services reconnected urgently.
