Another bad day.

So we went to the store(me and my mom) to get the money back for my laptop. And whenever my mom is going to return something she is known for getting her will through. But for some reason she didn´t even try to get anything good out of it. Usually she yells or does something but this time when it was about me and not my brother it is just fine for them to take my laptop for 5 weeks without a reason. It feels so unfair. And there is like he said a "law" that says that i can´t get my money back until it has happened 3 times and i have a feeling they will take as much time as possible just so the warranty dies out. Hoping for a better day.
