Product: Mortgage

Hello, I signed up for mortgage with Calber Home Loans in XXXX of XXXX, My first payment was on XX/XX/XXXX which has the escrow account build in as well. The first month I was informed my loan was sold and my escrow payment change. I will break down my payments below and the escrow increase thro out the year. 
Original signed payments with taxes and insurance at the date the loan was sign {$1600.00}, Every month the company was executing escrow analysis on the loan and changing the amount of my payment, XXXX of XXXX my payment went to {$1700.00} followed by another analysis XXXX payment {$1.00} XXXX, another analysis again XXXX payment {$1700.00} and followed by another analysis in XXXX and new payment of {$2200.00} XXXX payment {$2100.00}. In last analysis in XX/XX/XXXX my escrow had shortage of {$2400.00}. 
I left several message for the escrow department to look into the issues thru out the year. In reflect to that my taxes or insurance amount did not change, when I contacted them XX/XX/XXXX I was advised they can run escrow analysis as they want, On XX/XX/XXXX I called them again to inquire about the escrow spoke with XXXX XXXX and he foward me letter explening the shortage on my escrow when in reality was not shortage but overage since my payment decrease. 
Every month I receive notification with the new escrow analysis of shortage, In XXXX i start the process of removing my PMI insurance in order to request the escrow account to be removed. Representatives provide that as resolution since my payment was dictated by monthly escrow analysis.. The final decision on the PMI was made on XX/XX/XXXX and was removed. 
On XX/XX/XXXX I submit request for my escrow account to be removed since i can not afford to make that additional payment of XXXX monthly. 
My request was denied with reason given Investment requirement not allow to remove the escrow, XXXX I was not inform that the terms of my loan were unlawful change once they sold my Loan to another investment I was only advise they sold my loan 1 month later after i sign for it, they should be some limitation on giving you the option to agree on that with time frame specially when the terms were changed. 
Secondly my escrow analysis should noy be ran every month and changing my payments certainly not a month after i sign for the loan. If the loan papers were prepared and I signed its because I can afford that payment, that is certainly deceptive action on their side to have that loan executed. 
Thirdly= my taxes were as follow School TaxesXXXX XXXX Property Taxes XXXX Total taxesXXXX. which was calculated with the loan papers so there should not be any shortage or change of payment amount At this time my consumer rights were certainly violated and deceptive practice was applied in order to attract the consumer. 
As a consumer I have the right to make changes if I am not able to make the new payment amount but no option was provided and certainly not a lawful executed reason for denail on escrow removal. 
I would like that matter to be closely examine and address with the proper institutions and regulators to prevent any further mislead and unlawful action on Caliber Home Loan side.
