Bot cannot send you item in the following cases:
1. You have blocked trade (logged in on the new device, recently changed the password / e-mail, changed the Steam Guard security settings, have VAC-ban, etc.).
2. Your inventory is set to "hidden" in Steam privacy settings (Check it)
3. Check your trade-link in profile and in Steam settings – they should match.
4. Bot is having problems with the Steam connection; it happens quite often, the problem is on the Steam's side. Bot could also be banned, in this case, contact the support and describe the problem in details ([email protected])
If you don't withdraw your item for 24 hours, its full cost is returned to your balance.
