WDF is happening with text for zp?

Before i used to get about 1800zp with about 1 dollar and a half, and with the PAYMO company I used to get 700zp for about 70 cents.

Now, its 1.5$ for only 400zp? And 0.70$ for 200 miserable zp??

WDF is happening...? seriously some1 tell me.. Did crossfire start giving them less zp per text messege??
