I had the pleasure of working with Ken the manager at the Ronkonkoma store and I couldn't be happier! What is normally a grueling experience due to the amount of time it takes and information you have to give, was actually very pleasant! Ken was very helpful and professional as he thoroughly explained the different plans offered and what would work for me best. I walked out with a great plan and the process was absolutely painless! I'd highly recommend coming to this store and asking for Ken! View on Google
