The links I see there go to Amazon, Current Connected, various vendors.
You would communicate with each through their website or contact info.
Will, the owner of this forum, gets a commission on sales through his links but otherwise is not involved in transactions.
He reviews products and makes videos. If a product or company's service is bad in his experience, he will say so. (and has deleted links, stops recommending them.)
If you have a problem with a specific product or vendor, after trying to resolve with them, go ahead and post a thread about your experience.
