  22. Priya (verified owner)

    I honestly had a doubt about how the product would be, still I gave it a try. The battery is working really good as of now. Thank you techie store. Though the delivery was one day beyond the stipulated date, the delivery boy was so irritating, we even had a quarrel, because he travelled about half kilometre more and didn’t find my address, so when he finally came with the package he just poured that frustration on me. It was he who made the mistake and he tried to place it on me. Isn’t it kinda normal that they’ll get the address wrong or will have to roam lil more, well even if I argued with him, I was so dejected. In future pls make sure that these delivery boys are lil more patient. Apart from that, the experience with you techie store was really good😊
