Horrible customer service

Had to get my s6 edge screen fixed under warranty. Consultants all of a sudden not aware of the warranty and another rude consultant just said there's an app to download for the warranty when you you purchase your handset and walked off. We were never told this and the consultant reckoned that we can send away the phone and wait for the quotation and get it done in about a months time. They are all clueless. The shop opened after 9. Consultants all sat there and didn't even offer help. Not that they know anything anyway.
