Requested assistance in finding specific strings on the Web site and received a prompt but incorrect link from Jim Clark. Because I didn't notice his error, my 6/30/20 order was not correct and didn't realize until after receiving the order. Continued via their preferred method of communication, *******@juststrings.com, on 7/11 and 7/19 with no response. Tried calling their 800 phone number as well as one shown on the invoice, on 7/7 and 7/20 respectively. Both numbers had the same recording about the phone not being operational due to Covid-19. That has become a common practice this year, thus understandable. However, am doubting the sincerity of the "100% satisfaction guarantee" (touted on a full page on the Web site). The key words there = "may return any unopened merchandise in resalable condition within 30 days of the original ship date" (minus $6.95 shipping). With no procedure there for a return/exchange, the natural next step = contact Customer Service. Perhaps Covid-19 has put them short-handed/busy, yet not responding to communication after the sale is not good. This order was my first one with the company, though, thus perhaps just bad luck.
