Really poor communication
Really poor communication. There was an error with my extension to file and Taxslayer sent me one single email notifying me that there was an issue on the day I tried to file. Because of all the irrelevant emails that Taxslayer sends me around Tax Day, it got lost in the shuffle and I never saw it. They sent exactly zero follow up emails about the error with the extension to file. It's been over two months since the failure to file and I'm just now finding out that it never filed. On top of that, Taxslayer can't even tell me what the error was, just that there was some kind of error relating to some kind of unspecified thing, so the error could easily be repeated.
