4th Month on us -NOT

So on the 2nd of April I recieved an email stating : Hi Joel FOURIE,

You're just one more payment away from getting a whole month of unbeatable local and international entertainment, live sport, award-winning movies and more - all on us! To qualify for this incredible offer, stay connected to DStv Premium by paying your account on time"

And now apparently not - Just received an sms that I need to pay my account this month what happend to my free month ?

Or was this just another marketing scheme ? **** promotion ?

If that is the case I might just have to cancel my subscription and rather use netflix
