Auction issues

I had 2 cars sell on auction was was trying to claim the credits and reclaim the other cars that did not sell well an error popped up saying could not contact horizon 4 servers try again later and when it refresed all the cars i sold were gone. Gone as in i was not able to collect the credits for them. Sad because that was just over a half a million credits i just lost and do not have the cars anymore either because they sold. It happened right at the end of my live stream that I just got finished doing not really happy about this since i was trying to save up money in the game for one of the locations.
