In XXXX of 2014, I received a delinquent notice from XXXX XXXX. I was informed that my note had been sold to XXXX by XXXX. I informed the customer service rep that I had not received a letter informing me of my note being serviced by a new provider and that I made my house payment on time to LoanCare. 
When XXXX purchased my loan, I called them to find out what was going on. A XXXX rep told me that I had no escrow balance, no homeowner 's insurance, and they were charging me their hazard insurance. A XXXX rep told me to resolve my escrow issue I would have to contact XXXX. When I contacted XXXX they told me XXXX is my servicer and I need to contact them. I was later informed later by XXXX they wanted {$1500.00} for advance deposit to escrow. I was informed that it was XXXX 's policy to keep a reserve of money up front for escrow. I refused to give them that much money up front. I told the rep, " I do not care about your policy, because that is not what I agreed to '' His reply was something like " I need to read my contract because XXXX can ask for whatever they want and I could lose my house ''. I informed the rep that I was paying my house insurance out of my pocket since both LoanCare and XXXX refused to reply to XXXX 's attempts to collect from both mortgage providers. I also wanted to know why such a large amount of money was being asked of me since my property tax was paid on XXXX XXXX, 2014 and XXXX took over XXXX XXXX, 2014. XXXX would have a complete year to collect escrow from me and according to my monthly statements LoanCare/Selene withhold an additional {$300.00} a month for escrow. I feel none of this would have ever happened if XXXX or both mortgage providers would have worked with me and addressed my questions. Instead I was met with threats of losing my home and constant remarks that I owe and just pay. I am also frustrated that later they increased my P & I payment from {$860.00} to over {$1000.00}. I was told that since I did not pay the {$1500.00} advance deposit that they altered my house payment to reflect the {$1500.00}. Under RESPA I can only be charged 2 months ' worth of escrow so the {$1500.00} is too much. I would have been fine with paying {$600.00} which is 2 months ' worth of escrow as long as they could explain why. I was also getting charged for hazard insurance because they would not recognize XXXX as my new insurer. In XXXX of 2014, I switched from XXXX insurance to XXXX, but XXXX kept saying they never received any notice from XXXX. XXXX rep gave me the days and times of when they tried to notify XXXX. I had the same issue with XXXX until XXXX of 2014 when XXXX setup a conference call with XXXX and myself. So I know I was being charged for an inflated hazard insurance and I also paid for my own house insurance in 2014. Also, under RESPA I should have received notification from both parties ( current lender & new firm ) 15 days before the date my new lender takes over the administration of my loan. I am so frustrated because, of the lack of professionalism shown to me. I have been hung up on, disconnected after waiting on hold for XXXX and when I did get someone most could not speak XXXX and just wanted me to make a payment. No rep was willing to help resolve the issue. I did speak with a XXXX who handles my property tax and according to her, in 2014 my property insurance was paid by the time XXXX took over the account. Since that was the case and I was paying out of pocket for my house insurance, then why did XXXX want an advanced escrow payment of {$1500.00}? 
I am willing to work this out, but I think my account needs a full audit which XXXX refuses to do. Now I 'm on the verge of getting foreclosed on and I did nothing wrong.
