StarSat failing to resolve customer's problem

Good day,<br> <br> As a StarSat/TopTv client for years now this morning on the 8th February 2015 I wake up to an error message saying my smart card is not authorised.<br> <br> With the above said, I then called the call centre for assistance of which I did not get and solution to this problem.<br> <br> My main problem is, I have been using the same card and a set top box for over 2 years until last night yet today I am told it's not authorised. I pay my subscription every month without a mistake yet today I can't get my picture which is what I am paying for.<br> <br> Truly this is really frustrating.<br> <br> Your assistance towards getting StarSat to help me would be highly appreciated<br>
