I signed up for Square Up a week ago and just starting using. there are so many bugs in the application. I have sent 14 emails today alone to support and NOT one has been answered. how does this company ever expect to stay in business without any customer support. I will be looking to their competitors fir a more reliable way to accept credit cards. very frustrating for a small business owner (and this service was recommended to us). Great idea that's POORLY executed!!!
