E16 error

My decoder was scrambled yesterday and after contacting dstv on facebook I was notified that I'm in arrears so I didn't want to make a fuss and decided to pay and sort it as I'm in no mood after a long day of work to argue payment. my decoder was unscrambled this afternoon at 5 and now just after 7 I have the same error message on my tv and a scrambled signal. It does not help to try contact their customer call line as by the time you reach an operator you have no airtime left and their self service app keeps telling me that my account is not found. Can they please up their game as we pay a lot of money for a service that is constantly down.
