Charger

So I bought my phone a little over 3 months ago & my charger just stopped working all of the sudden like a month after I got it. Luckily I’m team apple so I had other chargers laying around that I’ve been using for the time being, but I want to know if I can get a replacement charger for free if I go into the apple store? I mean the charger stays in one spot, I do t take it with me ever so I don’t know how it could have been damaged at all. I just really don’t want to have to buy a brand new charger because the store sold me a faulty changer
