TshirtEcommerce plug-in [HELP]


I had bought this plugin: https://codecanyon.net/item/woocommerce-custom-product-designer/10959830

Along with the ultimate add-on plugin that attach to it. The plug in is fairly good but there are a lot of bugs with it at crucial areas. I have been unable to get adequate support from them. After 4 months of communication with them to try to get help and even repeatedly offering to pay them for their assistance they have only managed to log into our site and reset it all to defaults twice causing us to have to restore the backup of the files and then they go unresponsive for weeks.

Two questions:

  1. Has anyone had experience with this plug-in that could be able to help with getting it working 100%?
  2. Since I bought this through codecanyon is their a support team through them could potentially help me?
