Mango airlines

I boarded mango airlines from CPT to DBN. On arrival at DBN airport my luggage case was ruined. My clothes full of dirt. I went straight to customers service to report and all I got was a lousy apology and a narration of terms and conditions. This is very disappointing as I expected them to take responsibility for the damages and reimburse my luggage case which was absolutely brand new which was bought just a day before my departure. The airline and it's personnel were negligent and that led to damaged goods. They don't care about our belongings all they care about is the fares and they hide their poor service behind the terms and conditions. The fact remains we expect them to take care of our belongs as well. It was a disappointing service. I need them to reimburse my bag that all.
