Freedompop Charged for no service, overcharged and lied about refunding Los Angeles California

Singned up for service in November 2016, selected a phone number and the service was supposed to be $0.99. But when the SIM arrived, I could not activated it as the particular phone that I was planning on using for Freedompop service was not unlocked therefore not eligible. So I thought, since the SIM not activated, meaning their service is never used, therefore they won't charge me, so I just put it aside. After that, I saw in my bank record something like I was charged by freedompop but I thought since the only amount that I agreed with them on was 99 cents, that's not a big deal, I will call them later and explain. But (normally I don't pay that much attention to my bank charge details) after couple months, I realized that Freedompop had been charging me each month $27.98 for nothing whatsoever!

So finally on May 15, 2017, I called and talked to an agent called "Evelyn" with the work ID 2749. At first she was rude and was flatly denying any responsibility, basically saying that even though the SIM was never activated they were still supposed to charge me, and the tone was basically that I am lying about not agreeing to be charged the amount that they have been charging me, basically they did nothing wrong. The conversation naturally bacame heated and when I asked for a supervisor, she said the supervisor is not available, and then all of sudden she said she's issuing me full refund. Surprise! Too good to be true? Yes, indeed.

She said she's issuing a refund at a total amount of $167.88, which is $27.98 times 6 since November 2016, and it would take 24 hours to be in my bank account. I told her  that I will give her 72 hours and call. Now here is the tricky part. Of course the refund never showed up in my account. I just called after 72 hours. Now, they blocked me out of the "eligible" caller to receive "free service over the phone" category, meaning they never have to face me on the phone since even their "refund" is fake.

Firstly, the service was supposed to be, and if ever were used, only $0.99/month, and they have been charging me. Secondly, nowhwere I agreed to them or ever signed up for any service that cost me $27.98, and they, while never providing me with any service, had been charging me this amount. Thirdly, they fooled me off with a fake promised about a fake refund which never was refunded to me.
