US Capital Advance Scam for a loan. Took $300 from me. Philadelphia Internet

I applied online for a loan and they approved me for $3000. I called the number they sent to me in an email and began the process. He told me to go to rite aid and purchases a $300 money pak card and activate it. I did so and gave him the code for the card and also gave him my account information to my bankone account. After I waited on the phone for 20 minutes he told me to go to my bank and check my account to see if the $3000 had gone into my account along with the $300 from the money pak. I checked the account and no money had been put into my account. I told him it didn't work and he put me on hold again for another 10 minutes. He then said that in order for the transaction to go through, I would have to purchase another $300 money pak and do the same thing. I told him I didnt want to do that and that I wanted my money back. He refused and now I'm left with $6 to my name with over due bills. All because I was scammed.
