DSTV not Working

My DSTV still not working and they said they will call me back am still waiting after two weeks still no help, when I call today they are telling me that they will stop it only on the 28th this is unfair for me because I paid for subscription that is not working why are they telling me that they can only stop it on the 28th meaning I have paid for a month for something that I didn't watch. AM GOING TO THE BANK TO REVERSE MY MONEY!!!!
