Wrong transfer - Please help

Dear all,
This morning, I intended to make a transfer from my metamask wallet to another wallet (hotbit exchange) but I could not complete it since there was a failure in the process.
Later, I tried to do it once again but I made an involuntary mistake and copied a contract instead of the wallet I pretended to send those funds to.
How I can solve this issue? Is it possible to cancel that transfer in orden to get back the coins? At the moment I can not see those coins on my wallet so I understand that the transfer has not been rejected.
