Manager lies and should be fired!!!

Over a month a my issue is not sorted. The manager Taariq does not respond to emails also. <br> I came in with water damage and got returned a phone with a cracked screen. Taariq states ALL galaxy note 4 screens cracks once opened. I'd love to know them why he states he gave me a water damaged phone which isn't cracked?? Also, he told me if I had my water damaged fixed elsewhere, I'd still have ADH for the broken screen he'd given me? Then when the call centre contacted me he told them a different story. He won't reply to my emails cos he knows what a **** he is!!! I demand my issue to be sorted cos he's behaviour and attitude and pathetic lies will not be tolerated!
