I have buy an techno mobile from this and that mobile shop on 20/08/2018. After buying of few month mobile is not working properly than i went to local service center than they upgraded this mobile now it is working properly but my memory card slot problem is not resolved he told me to come after 1 month as my warranty period is not over. But today again went to this service center they are telling that memory card slot is broken they cannot replace. But my question is that after buying this mobile i have never use memory card than how i have damage this memory card slot. As a customer i want to know what is the use of giving warranty period. I never mind if you are not changing the slot but the image of your company will loss. I have suggested many people for buying your products. But today i will not suggest any body else. Thank you.
