Product: Debt collection

I am writing to file a complain about my dispute on my previous apartment XXXX XXXX XXXX XXXX   situated in XXXX California. I rented my unit last XX/XX/2018 for the amount of {$1700.00} per month. On our first month we experienced odd and scary events, we immediately called the attention of the Community Manager and our Agent but they don't have explanation whatsoever on our complain and nothing happened. Since it was only our first month so we decided to continue our rent and ignored the strangest events in our unit.Days and week passed it became more aggressive and scary. We still ignore and continue our rent. But something horrible happened last XXXX and we came to the point that we sleep in our car or sometimes we will go to hotel to spent our night and be back on the following morning to our apartment. We all know that it is so costly to move to another apartment aside from the security deposit they mandated to comply, the cost of the movers are expensive too. Finding a new place was also exhausting and stressful. Not to mention the damages and trauma that we experienced on our unit. We decided to move and transfer to another apartment last XXXX but prior to that we talked to the Community Manager and Regional Manager regarding our case. They offered us options 1. We transfer to another unit 2. We move anytime before XXXX XXXX and they will refund whatever amount will left on our rent plus our security deposit. We chose # 2 option and we moved out and transfer to another Apartment last  XX/XX/2018. We also agreed that we will not pay for the break lease contract amounting to {$3500.00}. Then last XX/XX/XXXX we received a letter from HUNTER WARFIELD regarding our debt balance from our rental at XXXX XXXX. We immediately called the office of XXXX  of HUNTER WARFIELD and told us ti settle the debts and  reconcile with XXXX XXXX. She also asked us if we got a letter or notice from XXXX XXXX XXXX XXXX   and we told them that we didn't received any notice or letter from XXXX XXXX. We called XXXX the Manager of XXXX XXXX XXXX XXXX and she told us she can't do anything about it. She promised us that she will talk and relay our message to XXXX the Regional Manager of XXXX XXXX. We waited for return call but nothing happened our calls are being forwarded to Voicemail, We even visited the Admin Office of XXXX XXXX XXXX in XXXX and no one talk to us, they are ignoring our calls. According to the letter that sent to us we are advise to pay {$3200.00} because of the interest of 7 % late fees & other charges may vary from day to day. It is so unfair in our part to pay such amount. Actually we are the victim here we pay for our rent that is so expensive and yet we can't even sleep at night in our own unit. Our life there was ABNORMAL. The stressed, Trauma and all the damages that we experienced was priceless. There is no amount of money to pay for your PEACE OF MIND. We just wanted to go out of that XXXX house and claim our peace. We know our story and experienced is a bit strange but we have witnesses to prove our claims. It is so unfair. The Regional Manager and the Community Manager are  both liar and unprofessional. 
I hope this matter will be put into light. Thanks
