4th Quest you need to pay ..... Just a friendly tip, every quest that has 4 quest to complete, it always has a pay method as the last one. The first 3 quest are free and the 4th quest has to be including money.
I won 5 battles like the first quest says, yet I got no points. You dont get 10 days to complete all the task. You get about a month for each task. The time resets after you complete one.
Quest 1 help Nevermind, I found it. You need to open your city tab from the World Map, then tap on the ā€œiā€ icon in the right bottom corner of your avatar and there will open statistic tab where you will find battles statistic.
