Selene Finance Mortgage Complaint

Selene Finance Mortgage department,

FHA mortgage Loan servicing, payments, escrow account Rhode Island

I have a complaint against my mortgage Co Selene Finance. - - - - -, T- - phone # -- - sold my mortgage to Selene. I had an agreement with - that if i paid before the end of the given month i would not be charge late fee. I was not behind on my mortgage. Once this was sold I also contacted Selene and asked them to do the same since we live pay check to pay check and my husband gets paid on the - sometimes going past the - which the mortage is due by. they would not comply with this. To make matters worse I was out of work due to an opperation and did not get paid right away. The mortage was due so we sent in $1100.00 not the full $1400.00. What we did pay was the principal and interest and some towards the escrow for taxes and insurance. They cashed the check but said they can not credit the account because they do not post partial payments. So now my statement shows $1100.00 unapplied and am considered late. I want them to post the $1100.00 and not consider me late. What else can I do. I also want them to work with me to not charge the late fees which are building up. What can I do. Please advise.
