Buzzmeeh — fraud done by company

Address:

New Delhi, Delhi, 110070

I have done my phone screen repaired from buzzmeeh company which is a very fraudulent company. They told me that we are giving you original screen and life time warranty. I am having invoice also in which it is clearly mentioned.
Now when my phone screen started having touch issues and half of my screen touch is not working and they are saying we cant change it as it is internal damage where as there is no scratch on my screen and it happened suddenly when i was in office.

I have tried calling them but they refused to help by saying that it is internal damage without even seeing my phone
