Lenovo — Camera not working for 4th time

I have purchased lenovo laptop on[protected]. In june 2020, , camera of the laptop was not working. On filing a complaint, a guy from technical support visited and repaired the camera.
Again in nov 2020, same problem pop up again and i requested for replacement of the product, but it was not replaced and technical guy was sent for repair. Again, in March 2021 same issue arises but there is no support from the company. They say it is in warranty of 1 year at time of purchase but when some problem arises, they say that replacement is possible only within 1 week of purchase. They are fooling customers. and there is no contact number for customer care. Again for 4 th time, I m facing same issue. This is disgusting on their part. Shame on Brand LENOVO
