Ripped after a week

My mum bought me this bag and I loved it. It was really cool and I had no problems with carrying it. It wasn't bulky or uncomfortable. After I had it a week with two text books and a reading book inside the entire side ripped open. It's a good bag but it can't handle anything more than a single laptop. It's very cheaply made. I loved it but it isn't worth anything if you can't put anything inside it without it ripping open.
