ETH stuck in a contract…

Hi, Yesterday I made a transaction of Ether between my old wallet to a new one. It was a test for me since it was the first time. It worked, I received the ether on my new wallet. All perfect.

But after I wanted to do second transaction between the same 2 wallets (with the same addresses), doing the same thing but here is what happened:

• I sent Ethers, but after 15min, I realized nothing changed, I did not receive anything on the new wallet and it was not deduce from my old wallet.
• So I decided to repeat the same operation. Then I went to sleep.
• When I woke up this morning, I saw that the ethers were still not added on my new wallet. So I checked the transaction status. The amount was deduced from my old wallet but I saw that it was transfered to a contract address, not my new wallet address. This is strange because I did not create a contract (I am far to know how to do this).

So the money is stuck on a contract wallet and I wanted to know what it means, how I can get these ethers on my wallet (either the old or new one, whatever) ? Do I need to validate something to trigger this contract (like a confirmation I made the transaction) ?

I give reward to the one who help me solving this please
