A bike shop would check bearing adjustment, gear adjustment, derailleur adjustment, nuts and bolts, true wheels, etc on any new bike out of the box. All things you can learn to do. For starters look on YouTube for front derailleur and rear derailleur adjustment and watch a few videos. Your bike may even show up but they all work basically the same. Hang the bike with rope from a rafter or tree so you can pedal it, observe and adjust. That will help you understand whats going on. Sounds like at least the front needs adjustment, something useful to know and be able to do yourself.
