JPMorgan Chase

I am writing to file a complaint against Chase Bank in regards to the following:
1. Improper and unprofessional services that Chase bank provided.
2. Received a harassment phone call from a teller Angela Araujo and an assistant Manager Mallorie Muncy from Chase Bank Branch in San Marcos.
3. Wrongfully accused my father regarding the overpayment of $100.
4. Violating our civil rights on accessing my father's checking account.
My father carried fifty 20 dollar bills, which total $1000, to Chase bank in San Marcos California for exchanging ten 100 dollar bills for me on April 2, 2011 around 11:00 a.m. Around 2:00 p.m., we received a phone call from a teller called Angela Araujo, who assisted my father at the bank. Ms Araujo states that she overpaid my father $100 earlier and would like my father to pay it back.
I asked Ms Araujo how did it happen, and she told me that my father wanted to exchange the bills and she overpaid my father during the transaction. I spoke with my father in regard to the situation. My father states that Ms Araujo counted the money twice, before she handed the total of $1000 back to him, which is the correct amount.
I explained the situation back to Ms. Araujo. I informed her that my father did not speak fluent English and I would like to represent my father to speak with the manager. After 10 minutes of waiting, no one responded.
Later that day, the bank manager, Mallorie Muncy called me back. She told me three different versions of the story. Version 1, Ms Muncy states my father only gave $900 worth of 20 dollar bills and Ms. Araujo returned $1000 worth of 100 dollar bills to my father. Version 2, Ms Muncy states my father only gave $900 worth of 20 dollar bills and Ms. Araujo returned $1100 worth of 100 dollar bills to my father. Version 3, Ms Muncy states my father only gave $920 worth of 20 dollar bills and Ms. Araujo returned $1100 worth of 100 dollar bills to my father.
I advised Ms. Muncy to review the surveillance tape, and I also requested to watch the clip to prove my father is innocence. The manager refused me to let me watch the tape and also said that once they find out, they will deduct $100 from my father's account.
We were very upset after the phone conversation with Ms Muncy. We felt extremely insulted and humiliated as Ms Araujo lost $100 dollar and they accused my father taking the money without any evidence.
Here are my questions and complaint:
1. Angela Araujo was not only serving my father, Chung Tak Chui, on April 2, 2011. Why did she only contact my father and stated that she overpaid my father?
2. Her story is not consistent and contradicting and they cannot just call and said that they overpaid my father and want my father to pay $100 back to them without any evidence.
3. They are wrongfully accusing my father about the overpayment of $100. If she states that she already knew it when my father was in the bank, then may I ask why Ms. Araujo and Ms. Muncy did not stop my father for the clarification before his departure? Based on their answer, Ms. Araujo already knows that she overpaid my father but he could not talk to my father as my father already left the building. This is not convincing, and they are ruining my father's reputation with their accusations.
4. Being a teller, it is her responsibility to count dollars bill correctly before they put bills into their drawer and they handed bills to the customers. They cannot just call the customers for any kind of problem; it is violating our privacy and striking our confident in their customer services. Not only that, they are also destroying my father's reputation.
5. This type of improper and ridiculous phone call is harassment. It is very unprofessional and we felt extremely insulted and humiliated by their accusations.
