Query: Very bad customer service

They still haven't fixed the error where electronic filing in California is disallowed due to incorrect address length calculation.Customer service of the company that makes this product is very bad. Customer service representatives are not knowledgeable and unwilling to help. This is why I am rating this product so low.[3/19/2007] I feel obligated to post this update: I was contacted by an H&R; Block representative, and was assured that the problem I reported will be fixed for next year.Apparently, this problem affects California state return e-filers whose address is between 25 and 30 characters.
