Liberty Tax/ Debbie Hyple Theft, not standing behind their guarentee, Somerset Pennsylvania

I received a letter from the irs about my 2012 tax return. After finding my 2012 tax packet, and speaking with the irs we came to the conclusion that my 2012 tax prepayer typed in the wrong amount off of my husbands w2. She typed in $644. The correct amount is $6444. This idiot forgot a #4!! So now we owe 1629. 

 So we took the papers into Liberty Tax along with our 2012 tax packet she said she needed to file an incident report with cooperate, and she apologized said theres no excuse I can give you, Im speechless blah blah blah and to give her one week. We gave her 2, and when we called to check  on things she then changed her attitude screaming at us saying she gave us our packet back, and she is only refunding the $458 we pd. her to do our taxes. 

Im totally lost. I have comntacted cooperate alot and Im just not understanding why this isnt being pd, Its no question she typed in the error, its not like I even touched her computer. This is what shes pd. to do and they should pay iy! So now they think Im gonna accept the refund of fee's. NOPE! Im contacting anyone I can and also called state cops and filed report for theft as she stole our packet!
