I purchased Woocommerce Simple Auction a while ago (3 months or so ago), but today my site manager tried to contact CodeCanyon to get some information, but was told that I never purchased the program. I wouldn’t be here if I didn’t, but I don’t know how to prove it. Any suggestions?
If you check your envato market profile you will see you are Member since March 2019. So, definitely you didn’t purchased as you mentioned you purchased 3 months or so ago.
Now I would like to recommend please make sure from which Envato market account you have purchased. Then loggedin from that account then go to Dashboard Download tab. Downloads and there you will find all of your purchased items.
