Managing an account: Checking or savings account

I had a check that I went to go deposit that was owed to me from a company that Ive worked for and I was sick in the hospital so when I got out, I came and deposited into my account. They told me it was gon na take time for it to clear OK my check cleared. The next day was deposited in my account and they took seven days. I went to tell her and ask him what was going on with my check. She said it was cleared and that I sent it to the back of Bank of America to their people and all of a sudden theyre lying about it being theyre lying about so many stuff and they close my account and they have my money I went to go try to cash a check they sent me back and they said that check was no longer to be cashed as it was already cashed in Bank of America cash it.
