Midland Mortgage a division of MidFirst Bank Escrow Account Ripoff Oklahoma City Oklahoma

 My sister  had a home mortgage with Midland Mortgage, which required  a portion of her property taxes to be paid and  escrowed each month.  She refianced her house with a new lender, the new lender required her to pay the property taxes at closing, which she did.    She then contacted Midland Mortgage to have the escrowed tax money refunded because the taxes had been paid., and provided them with proof they where paid.   She was informed by Midland they had paid the taxes.   She asked them  to provide proof of their payment, (ie a canceled cheeck, electronic funds transfer receipt).   Instead  she was sent me a letter that just  stating they had paid it and if she had any further questions she could visit their website.  She tried to contacted the person who signed the letter, but no one at midland seems to know this person or their phone extension?   Being unable to speak with the author of this letter, she went back down to her Tax agency  in PA,  showed them the letter Midland had provided as proof of payment, (which by the way isnt proof of anything ) they have no record of Midland making any tax payment for her property.  The only record they have of paid taxes on this property  show my sister check number. They further showed her how their system is  design in a manner that would  prevent a duplicate payment.   She then returned home,  contacted Midland again, explain to them what she had learns from  the tax agency, and again asked for proof of their payment.  To date she has made 15 phone calls to Midland over the pass 6 weeks, asking for thier proof of payment, which they are unable or unwilling  to provide.   Her mortgage broker told her to contact the Consumer Financial Protection Bureau who informed  her this was not the first time they where hearing this complaint and suggested  she contact PA and OK Attorney General and file a complaint.   I am sharing this issues for two reasons, first has any one else had this happen and second what elese can she do to recover this money? 

Thanks,
