United Cash Loan www.miamination.com They Supposedly said they deposited $300.00 in my account and saying that the company is taking it to the credit bureau Internet

I just received a phone call from a unknown number and they left a voicemail. It was hard to understand the voicemail so they gave me a number and I called.  When I called they told me that I have a credit that was being forwarded to my credit that I owe United Cash Loans $300.00.  So I told them wait 1 Minute and I went through my account and told them that I dont owe them no money because nothing was deposited in my account so they went on to say that they was going to stop calling me and forward it to a higher source
