Words can't even express how dissappointed I am in this service. I sent my books out the day after I submitted them for trade. The books were received and signed for by ziffit on August 5th. Today is the 31st they still have not sent funds and I have emailed them multiple times only to get the same generic response. They have emailed me stating they haven't heard from me, that they never received my books, and now this morning I wake up to my order being EXPIRED while they are " awaiting scan" tried reaching out many times and of course still just robotic replies. Feels like a scam to me at this point. US_61689 *REVISED* I was finally able to get in touch with someone to handle my issues. They replied fairly quickly and provided pending payment for today. For anyone having trouble contacting them I used facebook messenger on their page and finally had success. I have changed my rating from 1 star to 3. I sympathize in having orders unfulfilled because of the pandemic however I wish they were not so difficult to get ahold of and that there was some form of communication besides a generic robot response when I emailed them.
