Disconnected even when account up to date

I was busy watching a program when an E16-4 error came on screen, stating my account is suspended because my account not up to date. I tried resolving the problem via the selfhelp and the *120* option, but both not available. I then had to call the helpdesk, and àfter holding on going through a long process, the problem was still not resolved. I used a lot of my airtime for an error that is not my wrong doing. Dstv should reimburse me for my airtime. Also they charged me for Showmax etc according to the lady that helped me on their helpdesk. I am suddenly paying R939 per month instead of R899. As soon as fibre is live in my area I am cancelling my dstv.
