Business ProfileforTaxpayer Advocate Group

I used the services of Xpress Tax Appeals ( (Xpress Tax Appeals by the Taxpayer Advocate Group LLC) to appeal my property taxes the last three years. The agreement was to appeal with no upfront fees and only split the first years gross savings after a successful appeal. On April 17, 2023, I received an invoice for $1223.13 (Invoice: #*****) for the successful reduction on my property tax appeal in 2022 for $1223.13 (Invoice: #*****). Because I did not have any problem on my two prior appeal services with TAG, I paid in good faith, and then I realized that my taxes had increased to almost double the prior year. I wrote an email to request a refund of the money. There were no reductions in property taxes as the appeal claims were not successful, therefore there was no successful gross savings to split with TAG. I sent them emails and they expressed no intention of refunding my money.As a consequence, my mortgage payments increased $600 a month, due to the large tax raise on my property. I'm requesting for ***** support and intervention for TAG to refund my money and I would like to inform BBB about the unethical and fraudulent practices of this company.
