I have found about 168 IDs (train: 157 , test: 11) that have paid total amount going over the total contract value. And I didn't even add the initial deposit to this. And 11 are in the test set. I checked if maybe there was upsell and only 108 of these IDs had upsell. Is there maybe any interest involved or error in data?
The customer should stop paying once the they reach 100% of contract value right? based on the explanation on the video or have i missed something?
many of them paid exactly the same amount over the expected value. i dont think it is a mistake. my intuition is that it some sort of penalty payment.
i am still not sure becuase look at what 'ID_PCF6SA0' and 'ID_DQ9JJEI' paid in the testset. They paid almost twice the contract value in one month. Also checked the Upsell date the hike and it happens months later the payment during the few couple of months after upsell are normal.
