They don't want to reverse my money..

I had bad experience with tyme bank I sent money to another bank account and there was a glitch and money went out 2 times..only one amount is reflecting. I've been trying to call tyme bank they are busy telling me that the money is reflecting in my account,but they are failing to tell me the account they reversed money to.and the investigation team is clueless. They don't even understand what they are talking about..
