Green Dot Bank Rip me off California

On 12-21-17 I purchased and item for one of my customer for 399.00 from Best Buy.  While trying to check out, I had to run my green dot card several times due to their system being mess up. I did ask the clerk if I was going to be charger more than one time and he gave me a business card saying to call them if I did. Next day i noticed several charges and credit to my account, but it all balanced out. Two days later I notive that Best Buy had credited me in exsess of 4K and I contated the store to let then know. With in a couple of day later the store took their monies back, which is fine since it did not belong to me anyway. On the folleing day Green Dot suspended my account. I have over 7500.00 in that account basically all of my moneys. I tryied calling and the recording keep saying that my account had been closed and that I would not be able to get another card. I was finally able to reach a human in the Phillipines who said my account was closed due to fraud. I asked him to tell me what fraud he was refering to but he would only keep saying that I no longer have access to my moneys. I metioned to the representative that the money in the account is my money and that they are stealing from me. I just happen to be moving too so now I have no way to pay or to get a place. This whole sytuation could have been avoided with some simple conversation. This bank has left me almost broke as I was receiving my paycheck, and basically had most of my funds in this account. They do not care to leave a person homeless or anything at all. I have been a customer of them for over 8 years and this is how they treat you when something looks susoicious. I did nothing wrong and now they are trying to steal 7500.00 from me. DO NOT USE THIS BANK>>
