I understand you are facing problems with connecting your shop with Facebook.
Could you please share more details about the issue? Are you using the Facebook for WooCommerce plugin? What’s the error you are getting? You can share the steps to replicate the problem too.

Thanks for clarifying what plugin your using. This particular forum is for questions which are directly related to the features and functionality of the free WooCommerce plugin. It does not, however, offer support for questions related to any extensions or themes which can work with WooCommerce.
For the Facebook for WooCommerce plugin, you can find the official support forum for that free plugin below.
If you post your question within this forum and include some specific details of the behaviour which you’re facing someone will be able to offer you some guidance with that.
