Itunes is providing the least user friendly service to its customers. Initially I was not able sign in and finally after fighting to log into my account the ITunes Store is down. I cannot buy anything or even update apps from the apps store. I also faced an issue when i purchased an entire tv show series but after just downloading the first episode it asked to purchase the rest by paying more dollars. I think Itunes takes money from customers and never put any effort in making the program and store work for its customers....

I wonder how one can play a game if this gets booted every 5 or 10 minutes. For a wonderful game like Destiny, they must be providing a good service to set a bar with their competitors but the horrible connection issues and frequent errors makes the game uninteresting. Is this company expecting its players to do raid and strikes every now and then? Sometimes I am just able to play one PVP game then all of a sudden it gets booted again which makes me more frustrated. Can anybody help me in this issue?
