Nabeta Travel Inc

I have been going to Nabeta for years and was satisfied. I recently received a letter from the IRS stating that I had put down the incorrect amount on my tax form and as a result owed them $1100 because of the mistake and interest that had been accruing. I looked back at my W2 from my employer and realized that Nabeta had put down an amount that was off by a few thousand dollars. I went back to Nabeta and asked them to help me on this. They said that after they put together my taxes that it was resposibility to verify that it was correct. I said to them but I paid you almost $200 to prepare my taxes so I did not think that I had to check anything. That's what I paid you to do. Isn't anybody doing a second check to ensure that everything is accurate? They said "No". I asked them to please look into this to see how they could help me because I did not have $1100 to pay the IRS. I followed up with them a few days later but they had done nothing to assist me after putting me in finanicial debt to the IRS due to THEIR mistake. I was very disappointed in how they handled this because I have been doing taxes with them for over 15 year as well as my children and spouse. None of us will be returning. Also, this was not the first time that they burned me and failed to make things right but the last time I put it down to an accident.
