[DooDooPoker] $75/hr **BEST VALUE** [2nl-100nl High Level MDA Coaching]

The fact is, DooDoo spent 8 hours on you. You pay coach for his time, not for the content he gives you.

If you buy a car for 10k, then after a few months see the same car being sold somewhere for only 5k, do you demand they give you back the difference? No. It would be absurd.
Things like solver solutions/MDA data will change their value over time. It's normal.

Unless he directly lied to you about something, you have no case here.
