How apple is helping IPhone 13pro max users who are having facing problem while doing video calls? The perosn m the other

How can we get solution of faulty i phone 13pro max device ? On the video calls the other person can't hear us smoothly ,many time the voice is dropped off / missed in between the conversation.

From last two months i am following up on my complainant but till date thr is no solution to it ... After replacing the device also the problem is same and i came to know thr is a fault on this model only as when i spoke to one of my friend with same model noticed her phone also have the same issue and i couldn't hear her properly ..

I am really looking forward Apple to take care of this issue...
