What our customers are saying

  • 1 out of 5full starempty starempty starempty starempty star
    I am sincerely sorry for any woman who has had to indulge customer service from Jacob at Grand Ave. He blatantly hit on me, asked for my instagram, asked to be invited to my Bday party, and talked about recreational drug use while assisting me...He ended up giving me a case that didn't fit my phone... the lock button didn't line up with the case and i kept screen shotting everything...had to go back for better customer service where the nice employee apologized for Jacob. If it was up to me I would have Jacob FIRED on the spot; lazy, too comfortable, and this is 2020-stop hitting on everyone you meet in public/come into contact with; its damn awkward. I hope you read all of this so you can avoid Jacob when you go in the store!
