I pay for 60 day's , not for 60 without + - 4 day's

To much time lost for waiting when you make server service's - in 2 months many time's I cant play in my free time becouse you ( Blizzard) do something with servers . Is it fair ? I pay for 60 day's = 60x24h=1440h
Every wednesday 10-12 H for service ? it's two days per month. One year = 24 day's I pay for nothing.
Sorry for my English but I'm sure you understand. Please respect my money
