I financed my house with a 15 yr, fixed rate mortgage and have paid mymortgage on time every month. Further, I have paid an additional $ XXXXto principal with each loan payment since the inception of the loan. 
Normally on fixed rate mortgages, the interest decreases while thepayment to principal increases as each payment is made. On theservicing of this mortgage, the interest that I pay fluctuates with everypayment and does not steadily decrease. For example, the interest thatwas posted on the statement dated XX/XX/XXXX of {$100.00} isslightly higher than the interest posted on XX/XX/XXXX of {$100.00}. Ibelieve that the allocation between principal is calculated incorrectly for afixed rate mortgage. I wrote to BB & T and received a timely response, but the letter does not address my concerns it merely cites that it is incompliance with CFPB regulations.
