Was anyone affected by CMC markets stuffup on MT4 yesterday?

They fed in wrong U/J prices and basically caused my account which was at $6900 to close out with a resulting balance of -$202 000.
No email sent. I had to inquire.
Later - a full day later - got $5900 back. still missing $1000
very disappointed with them and will be leaving them once i get my money

what s theyr hole name? core liquidity markets from AU? or some other broker?
