Very poor service of Titan eye plus. Review on Titan Sunglasses

I was using the Titan eyes plus for few months they have very poor service . One day my spectes was broken so I thought to buy new spectes so I was going for new spectes toTitan eyes plus showroom so my brother said I also have to purchase zero power spectes because he was sitting most of the time infront of laptop because he is doing btech from computer engineering so we both went to showroom of Titan eyes plus so we were explaining the sellsmen but I was not able to get want we are asking for after 20 min he understand for what we are asking for. Then we both purchases the spectes of titan eye plus in 4999 and after few day I collected my spectes and I found defect in my spectes and I complaints to the sellsmen but they said we do any thing for that they were ignoring me and I forced them very much but it was useless for me so please don't buy titan eye plus spectes.
