Blackhawk Network PayPower stole my money and now ignores me about it Pleasanton California

I used the service Tmobile prepaid debit card from Blackhawk Network. After a couple weeks I tried to buy something at the store and it wouldn't go through. I called them and after 30 minutes on the phone, I found out that they had blocked my card for some reason. The customer service representative told me they didn't know and it would take 3-5 days to receive a response after it had been escalated. So after loading my card with cash, I was now unable to access it until they investigated the card for a reason I couldnt be told..

After 5 days, I receive a call from someone in the Fraud Department that tells me to email them a picture of my ID and Prepaid card for verification. I do this and wait ONE WEEK. No resolution. I call again and after 30 minutes, I am escalated to the supervisor that identified himself only as Adam - Employee 0024. I explain my situation and he tells me that the case was closed and I wouldn't be refunded the money. I tried to explain that I was called a few days ago and told everything was alright and to submit the documents. He gave me an email address and phone number for someone supposedly higher up to help me but the email address and the phone number were NEITHER IN SERVICE. I asked him more questions regarding the email and phone number and he grew frustrated and HUNG UP the phone on me.

I am only trying to receive my money that is still stuck on the prepaid card. $541.55.

They claim there is nothing there but I can still log on my account and see my balance. They have stolen my money and are giving any excuse to not give it back.
