Western Union Took money out of my account and won't return it ,said they're investigating...It's been 38 days now, Miami Florida

I've used Western Union for online wire transfer for over a year and a half now, and I was happy even with the occasional headaches caused by their horrible website. Then during the whole month of august 2014 their website started acting out again. 

On August 5th 2014, I made 1 wire transfer. A few minutes later I received an email saying that the the transfer had been cancelled. So I logged in and repeated the transfer, again a few minutes later I got another email saying that the transfer had been cancelled. So I gave up and went to a Western Union location and made the wire transfer there. This time they took a couple of days to email me saying that the transfer had been cancelled again.

So I called them and they blamed the bank overseas where i sent the money to. They said that the bank is not accepting the transfer, so I asked the receiver to go to the bank and ask why they're not accepting the tansfers and they said there's never been a problem and they are accepting the transfers as usual. By this time I had called them about 5 times and every representative I spoke with gave me a different excuse. Some of them told me straight up "I don't know" (Note that some of them spoke English very poorly, so we had difficulty communicating)

They told me to go back to the Western Union location and get my money back for the failed transfer I had done there, which I did, and got reimbursed.

They also told that, for the two online transfers, they would return the money (US$671.00) back into my bank account in about 5 days.

Well today is September 13 2014 (38 days later) and the money was not paid to my receiver nor did it come back to my bank account. I keep calling and asking for my money to be returned and all they say is "We're investigating"

I filled a complaint with a county consumer protection agency. I'll file another one with the State of Florida. and then a federal complaint until the money is returned.

Advice: Do not use western Union if you don't have to: Website malfunctions very often, customer service is not knowledgeable enough to help with issues (when you get one that speaks English well),  and unethical business practices.
