Scanner Master received my PSR-800 on Monday, Feb 23rd, per the USPS tracking system. 31 days later, and a "one line response" that it was to be shipped back this week, that being the week of March 23rd. "Not Impressed", wraps up my general opinion, to perform updating of my device, as well as there lack of dialogue, to explain the amount of time that has passed. Sadly, at this moment, a "letter grade" of D, is my overall public opinion of their customer service. I had a previous "run in" with their customer service rep, when I ordered 2 "Deluxe" printed Rad Ref frequency booklets, and upon examination, one booklet contained the correct amount of info/pages, and the second did not. A lengthy argument ensued, as I stood my ground, stating I was billed for 2 deluxe editions but received a "slimmed down" version, so either mail the additional pages,or credit my debit account for the missing portions.I then received loose pages of the second printout, and had to "restaple" the modified booklet together. Since both "Deluxe" editions were for different "Counties" in New Jersey, they decided that I was to receive the full edition on one booklet, and a "reduced" booklet on the other edition. These were 2 separate clients, that I was providing the Deluxe County Editions to, so an apology to these accounts was forthcoming. I hope folks have a better experience than I had, with this organization.
