@JaeD sorry to hear that you are having issues with your TA. I really do find that this is such an important part of the wedding planning and it makes all the difference to find a TA that works for you and that you trust.
You may want to check out this thread about TAs in the GTA. I posted a review about Karen Lantigua at myweddingaway.com who is my TA and I love working with her. There are some other great suggestions on this thread as well. Happy planning!
