Titan Eye Plus — Poor quality of lenses. peeled off of lense coating

Dear Sir/ Madam, I have bought 1 pair of glasses frames + lenses ( Lens Fsv white titan) worth rupees 4065 on dated 28th January 2014 from titan eye plus having sale order TMVS018406 and invoice no. BBA0017095 but within 18 months the lenses coating got literally peeled off even without using it much. i have purchased the lenses worth rupees 1750 without discount but the cost did not worth for me. Since this is such a poor quality of the lenses which could not expect from titan. During the purchase of the lenses titan sale person has been told that these are the finest lenses and which will be last long at least 5 years. But within a year and six month means like as soon as warranty finished lenses got peeled off which we can see by nude eyes and can feel by hand. I have visited to titan store airoli, navi mumbai branch and they have told me that i have to bear at least 75% of lenses charges then they will replace the lenses. I have to mention here that peeled of lenses coating is not my fault then how could i bear charge for new lenses? it is poor quality of titan with high prices. Which is making trouble to the customers after paying high charges. titan eye plus should have to consider about inconvenience occurring to customer. I hope titan will note my complaint and will give me refund or replacement of new lenses free of cost. Looking ahead to hear from you soon.
