Unhappy and dissapointed

towards the end of last month, dstv called me an offered me the dstv explora ultra and i was told that installation will be free, i took the offer. last week i was disconnected and there was an amount of R438 that i had to pay, for installation , that i was told that it's free. i payed the amount this morning. when i called to ask for reconnection i was then told that for them to reconnect me i have to pay an additional amount of R570 for the subscription and i didnt watch dstv for almost 2 weeks but they're charging me the whole R570. Dstv is a ****, really.
