Lenovo — Lenovo phab plus tablet (pb1 770m)

Address:

New Delhi, Delhi, 110019

Product serial no hgeh12me
I have lenovo phab tablet pb1 770m
I am facing problems with this table the product quality and customer service (India) leaving me only frustrated.
First my tab already had motherboard replaced by lenovo service centre. The problem now is that tablet has very poor camera quality (Almost vga quality) second it is not accepting 32gb micro sd card.
I was told by customer representative mr. Tanveer (G17, 18 hemkunt chambers, nehru place, delhi, india) that blur picture for this tab is normal and second that it does not support micro sd card beyond 16gb.
Both arguments are not in line with product features on lenovo website.
I am not satisfied with customer representative response and feeling letdown.
Kindly suggest what to do.
The tab is submitted to service centre today after i insist.
