Jabong.com — ml courier has no relation with jabong

I placed an order for a shirt and trouser with jabong.com with tracking id mljc2220067 on 25th of january, 2018 and my order has been shipped on 27th of jan, 2018 through ml courier but when i tried to track my order on ml courier website, it showed that they have no relation with jabong. I couldn't understand how can a courier partner say this? I m confused!
