Loancare LLC Stay Away if Possible

Back in November I did a refi through a local bank (Progressive) to get a better interest rate.
It went through and was sold to another local bank (Origin) as expected. I knew about that in advance.
The problems arose when Origin sold my mortgage again to LoanCare, LLC a division of Service Link Companies.
They've taken and processes all mortgage payments without issue.

The problem is getting them to pay parish property taxes.
It shows in the account the amount of tax to be paid.
The payment was due on 12/31/2017. I figured they had paid it. About 3 weeks ago I get a certified letter from the parish saying that the taxes are deliquent and fines/fees have been attached.
I call the tax assessors office and sure enough they were not paid.
I called the mortgage company, got an issue number and supposedly they will be paid by the end of this month.

I called the tax office again and of course they have not been paid.
Called LoanCare again and they appologized again and promised that they will absorb and that the payment will be there by 03/31/2018. I expressed my doubts and the agent claimed that they can "wire" the money to the parish office.
Called tax office and they do not have the ability to receive "wired" payments. This certainly doesn't surprise me regarding Ouchita parish.

I'm about ready to sue the mortgage company. I don't seem to have any other recourse.
