Deplorable customer service. My envelopes were printed incorrectly and it took over 2 weeks for new ones to arrive (plus several calls I had to make to their rude customer service representatives who knew nothing about the reprint request). I originally paid for express shipping and had to wait weeks for correct envelopes to arrive. They were printed with 2 zip codes on them and the excel spreadsheet deletes 0's from the beginning of zip codes so 4 digit zip codes were printed on the envelope (I had made note of this in my original message and warned them that the zip codes were missing a number in the required excel spreadsheet but nobody apparently read that or called me to clarify). When I call customer service to discuss these things, they treated me like I did something wrong, didn't take any responsibility for their mistake, and didn't offer any kind of apology for taking weeks to respond to my request and my phone calls.
