Ok plug-in with poor customer service

The plug-in is easy to use but doesn’t do what it says any more than Jetpack in my experience: hashtags added in the editor don’t appear on Tweets; paying for the Large Card Summary and the supposed pro customer support is pointless. I paid, have the problems above plus problems with Twitter accepting the Large Card Summary code so took up the developers ‘supposed’ offer of easy and available ‘Avenger’ support. I used the customer service form twice and nothing has changed 3 weeks later and no response from the developer. To be honest I’m not impressed.
