Type of trade: Dreikt was to complete some quests on my account
How he scammed: Perhaps not a scam, but very poor trading practices

Explanation: Dreikt was to complete the following quests for me:
- DS2
- Kingdom Divided
- MM2
- Night at the Theater
- Song of the Elves
- Sins of the Father (currently in progress. not sure how far in)

He finished Sins of the Father (just the bossfight) and DS2. He said he'd do it in 1 day, but it has now been 10 days and he isn't even halfway. He communicated that he had some delay, which was fine but I haven't heard from him for 4 days. I messaged him 2 days ago, got no reply. Logged in on the acc, last logged in 8h ago. He even sold the Marks of Grace and full graceful: https://i.imgur.com/ZAi1Jl6.png
I left him the account with ~12m bank,it now has roughly 1.5m.

I don't think he owes me nor I owe him, as the 10.5m is roughly what he'd have made with the quests he did. I do think he should get a TWC for poor trading practices.
