I know what individual did this and had the same problem. Here is what happened to me as I described in a message to WGT: (I was refunded)
I made a request on September 6th, 2015 regarding the same matter as
today! I still have the email that you wrote and did everything you told
me. I have submitted a report by right clicking on the screen. I lost
1,600 credits this time again to my opponent. I am thinking this
is either a course problem or an individual cheating the system (I think it is a lag switch cheat tool); it was
the same problem after being 1 up through 1. Their screen was loading
and after waiting 2-3 minutes I had to disconnect and wait for them to
connect. I did this twice, then he disconnected (which should be their
3rd one because I waiting 3 minutes each time, but it didn't count as a disconnect) but I got the Error
Message and lost 1,600 credits.
I am not going to play this
individual again, that's 3,600 credits I have lost (the first 2,000
9/6/2015 was refunded back to me). I just find it suspicious and would
love an answer, the opponent is claiming it not to be my fault and has
already deleted my messages.
Now Yiannis1970 has had problems with the individual! I didn't name the person, but his name is on our profiles.
