Charge for a service that disappears

I have paid for a DSTV Drifta every month for years. Some 4 weeks ago I was unable to connect as the mobile device I was connecting with, reported: "unable to connect to authentication server" Reported the fault to the call desk, A Service centre-(I was sent there by the call desk). I reported via the web page and got this reply: "Enquiry Reference Number: ********** Good day, Thank you for your email. Kindly note that the Drifter App is no longer valid. Please note that you will not be able to use the Drifter as it is obsolete. It has been a pleasure assisting you. Kind regards, Kedibone Diala"

Only an arrogant organisation like MC can terminated a service for which a subscriber is paying (and has invested in the device) with telling ANYONE including the people who are supposed to serve their customers- most of which did not have a clue what I was talking about. I expect to be recompensed!!!!
