What should I do?

[FIXED LOOK COMMENTS] (Samsung s9+) So i inserted by mistake my sim key into the top microphone and my mic. isn t working anymore(i have tested it )just bought the phone the other day It s not that much of a big deal since a still have the bottom one but i am quite stressed. I am wooried about giving my phone to the company i bought it from to repair it because maybe in the future i will find some more issues because they didn t do a great job(for example) and i heared ppl complaining about issues after they got the phone back from the repair service. So should i leave it like this? Or i go fix it.
