fender squier amp

My Fender Amplifier is doing weird stuff?
Okay well, my Fender amp has been doing weird stuff okay so when ever I’m playing it’s like the volume just shuts off (and i didn’t hit the volume knob while playing) and then it just comes back on and keeps on doing that. I just got it in march and it has been used before. So should I take it back and have it replaced or what? And I don’t think it’s my guitar (Squier Strat.) because it plays fine at my lessons.
So what do you think i should do?
take it back and have them check it,also checkyour volume control on your guitar.
