My refund request was rejected, because the software that I purchased was... old (according to the official answer that I received from seoclerks). My purchase was in 2019. Unfortunately the software stopped working. The seller ignores me and his software is still for sale on seoclerks. If you want to buy software or services, I just inform you that after some time (obviously less than a year) if something goes wrong you will not get refund.
I trusted seoclerks but not any more...
