Canasta

I LOVE playing Canasta and I play descent but I noticed, even when I win, I lose points.  A person I'm playing quits before the end of game because she is losing, and a bot comes on and I continue till I win and I lost points.  Does that compute to you?   I have gotten VERY frustrated with this particular game perimeters because the other person ALWAYS gets a canasta first or second play and my hand has maybe one or two of the three-of-a kind... The computer is definitely siding with my opponent consistently and I play every day.   Can something be done with this?   My frustration level is that I'm wanting to quit pogo because of it.  I love that game alot and hope it can be fixed.  Thank you
