It is ongoing right now. I bought the plane about 1 year ago and have been going through this since. Having to wait a month or so for each of the containers to arrive from China and then waiting on the wing set TBM said was being shipped that day. Only to find out they had lied about it being shipped when they actually sold it to someone else to turn a profit from my replacement parts.
Weeks and months add up.
I guess they assume if they put you off long enough you'll just go away and they consider that profitable.
