I withdrew coins from Poloniex today and never saw the coins come into my wallet 

I am new to this coin so maybe I did something wrong.  i dont know.  I created an unregistered account and used the account key as the address.  I did not add a memo so I don't know if that made a difference.  I couldn't find anything about these transactions in the block explorer so I don't know what's going on with that.
Any help would be appreciated.   Thanks in advance.

These are the transactions from Poloniex.  They said they were working on it but it's been 10 hours already and nothing.
