You were awarded the right amount. There is a bug in the more special offers section where if you complete or quit a task, and click on the link which sends you back to more available tasks, it then shows incorrect amounts. This is something FusionCash is aware of and can't fix, as it is an issue with the provider of the tasks. It is recommended after finishing a task, or quitting one, to go back and re-open the 'More Special Offers' through the offers page on FusionCash to see the correct amounts.
I agree that tasks can be long, onerous, and tiring, but a reward of $1.20 is actually a good amount for a task, believe it or not. Most are under $0.50 and take similar amounts of time. The tasks aren't for everyone. Your best bet is to try several different kinds when you have the time. When you find one which you either like, or isn't very hard or long, keep an eye out for future ones, as many will re-appear over time.
