Very unprofessional business

I was a client of Gee, Lambert and Courneya for about 25 years. In 2012, my accountant Bob Courneya informed me that he would no longer be able to prepare my US tax returns. I found another accountant who could do it but he discovered many problems with the Canadian tax return which necessitated a lot of wok. He ended up billing me $900.00. I wrote to Mr. Courneya asking him or his firm to reimburse me this amount of money. Despite my long-term relationship with him and his firm, he did not even give me the courtesy of an acknowledgement of my letter. I followed this up with another letter to his associate, Douglas Lambert. Again, no response. If you're interested in being treated in such a rude manner after there has been an issue, then hire this firm to do your accounting work. If not, give them a BIG PASS!
