BBVA compass slole 5,200 and then they close our account without informing us by call or letter.. Been their customer for more than 1 year Dallas, Texas Nationwide

BBVA compass stole 5,200 money from our account without notification via phone or letter. They close our account after they stole it. We called and they said we lack information and they send us the papers that need to filled out. We have been their customer for more than a year and all our automatic payments goes to them. Since we did not receive any letter or papers they said that we need to fill  them out so we went to the bank. They help us fill out the papers.  BUt until now they have not returned our money from the account. We talk to the customer service and ask for the superviser. The supervisor named Maylene told us she will call us on Monday to help us about our account  but she never did. We called the next day and she was in sick leave. We called again in the next day and they said there are two Maylene and they are all in their breaks so they will call us but they never did. They have given us excuses every time we call. We trusted this bank so much and yet they treat us like this. We never knew what happened to our stolen money until now. We did our part and went to the bank and fill up the papers yet they disregard us. Justice please
