I made 2 Bitcoin transactions with Yobit both received over 2 confirmations each and still wont show under pending deposits. I messaged support and they sent me this

There response Delayed (464134 blocks)

What does Delayed (464134 blocks) mean? They have my Bitcoin because the Bitcoin had multiple confirmations. Does this mean they are going to hold onto my Bitcoin for 464134 blocks??? If so each block is 10 mins which equals 4,641,340 mins!!!! So in over 3,100 days which is around 10 years my Bitcoin they already have in their position will be available on my account?

Here's my two deposits
