FRUSTRATED AND DISAPPOINTED

I SUBSCRIBED FOR THE DSTV INTERNET TWO WEEKS AGO AND IT WAS DELIVERED A WEEK AGO, I MEAN A DAY BEFORE MY DSTV WAS DUE AND I PAID BOTH ONLY TO FIND OUT THE ROUTER IS NOT WORKING TILL TODAY, I WENT TO DSTV IN KING WILLIAMS TOWN AND IT WAS ACTIVATED WHEN I CAME TO THE HOUSE, IT'S NOT WORKING AGAIN I WENT TO THE EXPRESS IN VINCENT, THEY CALLED THEM AND THEY SAID IT WAS A RANDOM SYSTEM ERROR AND THEY WILL COME BACK TO ME WITHIN 48 HOURS THAT WAS ON THE 19TH FEB TILL TODAY NOBODY HAS CALLED ME AND IT STILL NOT WORKING YET THEY WILL EXPECT THE FULL PAYMENT ON THE NEXT PAYMENT... IT'S FRUSTRATING AND NOT FAIR...
