You are wrong bro. Forum and Social media are very helpful in promoting products or referral links. They are not interested maybe because everytime they visit your page, their is incomplete information of yours. To be legit, you should post your product. Its purpose and used. Also, you should post your transaction to other people. Like posting picture that your client received your product. Or the receipt from courier, you can post it also. Also, in promoting products, you need also patients and need some strategies to recognized easily your product.
