Unusable and unsupported

This plugin has too many bugs to list. It simply doesn’t calculate correctly, it you refresh or change anything it behaves odd, such as giving away free shipping. Support is worse than terrible. At first they asked for all of my passwords to my entire domain and website because they are too lazy to remote with me to work through the issues then they basically said that they know it is useless, but it is free. After asking me for lots of info and screenshots they stopped replying and despite multiple attempts to get in contact they won’t respond. After two weeks with shipping that doesn’t work and no response from their support I’ve removed the plugin and am using a real shipping plugin that works.
