925-415-9148 Give them a call
i have had no issues with them. if they don't answer, i leave a voicemail and they call me back within a couple hours
I highly doubt they are going to avoid you because you own an n55. a business wont do that and its not like they have any reason to. Even if most their sales are for the n54, why would they avoid n55 owners. Remember, they sell alot more than just piggybacks.
