Product: Credit card or prepaid card

This document is going to be written with my XXXX XXXX  program and each complaint and agency I contact with this dispute request or information will be given the same document. I feel that this is a way to assure consistency within my dispute, and unlike the companies I have contacted I do not want any discrepancies in what has occurred, what I have requested, submitted and above all what has been an empty search with no help. This assures everyone receives the full and unbiased information. 
I am very unhappy and am appalled at the disconcern towards me and my dilemma. 
I purchased XXXX prepaid cards from the local XXXX XXXX  XXXX XXXX  in my area. I had closed a bank account and needed to pay my rent. We always do that digitally online and mostly thru XXXX. 
I inquired to great lengths about the cards as I am not all that familiar and was assured that 2 cards would be uploaded with my funds that I could use now or at a later date. I purchased a net spend visa and a net spend XXXX. The attendant took my XXXX per card and gave me a receipt for the transaction. ( enclosed here ) I also received a smiths receipt that also showed the transaction. I thanked her and left. 
I had opened the XXXX card to get a closer look to see if it was like the one the XXXX service sent me. Then put both back in my purse and went home to sleep for a few hours as I worked graveyards. 
I went to work and planned on sending the money on the cards to pay the rent when I had my lunch break. I was a XXXX  so I have a private area and a shelve I keep my things on. 
When I went to my purse at my lunchtime the cards were gone and all that remained was the back to the XXXX card I had opened remained. I immediately notified my supervisor and in the morning before I left I told the secretary at the front desk and she said if she saw or heard anything she would notify me. This was the morning of the XXXX. Later that day after I was home I contacted XXXX. ( the number on the receipt. I was told then they had no way of tracing the cards or could they stop payment. I could not get the card numbers either. I thought that odd as they were the ones who loaded the cards so somehow, they had the info to send the money. But they said no. They said call Net spend and I could be refunded. I did. They said they have no way of knowing the cards ( Even though I have a verification link and number to show the cards were loaded ) and until they were used the numbers on the cards were going to be unknown. Now I was mad and my next time I could do anything was the day after the next, I think it was the XXXX or XXXX. I went to the store, ( XXXX ) and inquired there. The manager was very rude and said to me quote I dont know what your trying to do but you are not walking out of here with a XXXX dollars I was blown away. They had my money! I wasnt trying to get a refund either. Only asking to buy new cards so I could get MY money. So it was shocking but she contacted someone corporate and wow,, they had the card numbers. But would not give me the exp dates or the sec num. so I was told to call net spend again. I did. They still deny any knowledge of the cards and said I didnt have the correct 16 digit num . also be carful because the store was lying to me. huh? This was getting even more frustrating. So again I called smiths. ( XXXX ) and again every day they referred me to the other. I got mad and on the XXXX, I went to XXXX corporate office here in XXXX XXXX. The doors are locked, I see people inside but I was ignored. I called again from the parking lot and again the same old run around but this time I was told that the credit card numbers they provided me with were not the actual 16 digit numbers to my cards. But I do know from the receipt they match the last 4 numbers. Each transaction had the 4 last numbers of the card. So I do not know what to do now. 
The biggest problem is I am now being evicted from my apt and my landlady thinks im a deadbeat. She doesnt believe the companies would do this and I must agree XXXX quite shocked myself. I have a XXXX XXXX XXXX mother who lives with me and XXXX is having a place to live or not. They dont care, but worst of all is I PAID THEM TO TAKE MY MONEY. No one will even tell me who has it. 
So what can I do??? Can anyone help? Can I sue them if I end up on the streets? And that is possible, we have no living relatives here. I am scared and dont know why this is being done to me/.
