Hi all, I got new reply from support which one have same tech. words after half a year. Here is the reply
Hi,
Thank you for your patience while we look into this matter.
As you have stated, a staff member in your employ has sent BTC to your USDTOMNI wallet. This is a cross-chain transaction, and as stated within the deposit message of USDTOMNI (along with all other currencies): Sending any other asset to this address may result in the loss of your deposit
We understand the frustration regarding this case, but this is something that we are attempting to rectify, but there is no timeline given, nor a guarantee of the recovery of said funds. Please also refer to our user agreement, specifically section 5 stating: If you send a Digital Asset to a Poloniex address that is unable to receive that specific Digital Asset, or if you make any typos or inaccuracies in the wallet address, such Digital Asset may be lost forever.
We will attempt to recover this transaction for you, and we will be in touch should/when we make any progress related to this matter.
I will reply support but before that I want to know your thoughts and What should I write them.. I found more post on bitcointalk which one got the same issue and Poloniex support solved that in 1 month but mine takes more then 6 month and dont have any solutions. I am afraid of that finally they will say me that it can not be recover. what I have to do ? Thanks..
