Tommy Hilfiger — bag

I purchased a bag with laptop space for college purpose in later january 2018.in no more than 10 days the bag started tearing off from the strap area. The cloth of the strap is of very bad quality that it is tearing off from multiple sides. I sent the bag to repair and got fixed in 15 days. But now the bag has again started tearing off from the same area. I demand replacement of the bag now since the bag cloth is of very bad quality and the company has failed to deliver the tough bag as promised. It is very frustrating. Even after repairing the bag has again started tearing off in not more than 15 days again. The bag is nor able to handle even the weight of few books leave aside the laptop.
