Titan Eye Plus — Urgent Solution Needed Facing Issue With Lenses TKT-[protected]

I got my eyes tested and ordered a new pair of lens which I received on 9th December but after that I am facing issues with that, the new lenses are causing me an eye strain which resulting in headache and tears from eyes and the same I communicated to the Titan store and visited again to check the problem but unfortunately they are not providing me any solution even they are saying me to wear the glasses for at least a week but how am I supposed to wear the glasses for the entire week when it causing me headache, tears and bit of blurred vision but still a wore the glasses for 2 days continuously now I cannot wear them any more.

I have visited store six times, I chose Titan because I wanted the best service which I assumed Titan would provide but no solution till now.
So please help me to get the issue resolved on priority basis.

My complaint number with Titan is TKT-[protected].
