OnePlus India — damaged case received with phone

Address:

Bangalore, Karnataka, 560043

Hi,
I brought oneplus 6t from oneplus official website and the silicon case with the phone was damaged when i opened it. It have so many scratches on the back of silicon case
After receiving the case i immediately called oneplus executive informing about the issue you guys can also check it at your end.

Since 2 weeks oneplus executives are telling me to wait as the case is out stock we will send u asap, i have it on recording as well that oneplus executive (Prince on 2nd dec 2019) told me logistic team has said that they will send it asap, but today i got a mail saying that it is intact condition what is going on with oneplus such a bad service
Everytime i call oneplus executive told me that your has been escalated its been more than 2 weeks now i never received till now
