If leaving a negative review is the only way to grab the attention of their non-responsive support team, then so be it. I purchased business calendar because of its outlook calendar sync feature, however the calendar requires an existing outlook account on the phone. I wanted a standalone outlook connector - One calendar app does a fine job there, this one fails. I asked for a refund the same day, and sent follow up emails too, but thus far no response. Useless support, don't deserve stars.
