I have an 18 month old manufactured housing mortgage with US Bank. At the end of XXXX they notified me of an escrow adjustment of {$2700.00} for taxes ( the first year and the next year ) to take effect XXXX/XXXX/15. This took my monthly payment from {$430.00} to {$750.00}! 
I promptly called the bank to alert them to a problem. I received the phone tree run around for 70 minutes. I explained to a Senior Banker XXXX that the amount was horribly inflated. My tax estimate last XXXX was {$880.00}. I also explained that the tax bill had n't yet been issued. She informed me that they got their information from my taxing authority and that I would n't see a bill and that the numbers were correct ( at best all incorrect or at worst lies ). 
A week later I received my tax bill and it was a few dollars less than the XXXX estimate. I sent a copy of the bill and relevant correspondence to the address the bank provided asking for a prompt adjustment. 
On XXXX XXXX I again called the bank. This time a chirpy Customer Service Rep informed me that there was a note on my account about a {$500.00} difference between " their estimate '' and the actual charges. She told me an investigation was underway and could take up to 90 days. She also informed me that I needed to pay the inflated amount until I was notified differently. She also added that I would receive any overpayment back in a " big fat check '' in XXXX. 
I 've continued to emphasize to the bank that they should not have made such a gross over estimate a week before the actual bill was to be received. I 've further stated that while I 'm sure the matter will ultimately be resolved it is difficult to pay the large, incorrect increase out of a retirement income!
