I really do think MA is trying to kill shops off. That is exactly what will happen when they implement teleporter fees lol.
Soc mate sold his booth for over 1/2 what he bought it for a year earlier because it went buggy just as yours did and support seemed to never take the case anywhere. So MA effectively is already reducing the price of shops/booths by making them unmanageable.
Also Ulf I think is where support cases go to be forgotten about, I have canceled and removed every support case run through him as he seems to never send them onto anyone and just puts them all in file 13, the little round file basket on the floor next to his desk that magically gets emptied nightly so the cases must have escalated someplace I am sure.
