Hi Mixed, just a thought, if the guitar is only 2 months old, why dont you offer to see if there is a problem, and then have it repaired or refunded under warranty.  Most guitars are covered by at least 12 months, and it could just be a case of adjusting or replacing the tuning pegs.  If it is drastic, such as the neck having too much flex from the body, and causing constant retuning (yes this happens on some new guitars), I would not be a happy buyer either.  Personally, I would take the guitar back with the offer to have it at least looked at, but no refund at this stage.
