Charger Warranty

Hi I bought a charger from apple a month ago and it is no longer working. Wires are not exposed and shows no visible wear and tear. Over the past few weeks (worked perfectly for barely two weeks) it has blinked from charging to not charging in a few seconds without the wire being bent in any way. It has not been water damaged either.

Will they replace this for me? And is it possible to do this without having to visit a store? I do not have one nearby
