Unfair To The Seller And The Buyer.

I think it is most unfair the Pinterest will not let a customer enter the sight without signing in. Furtherthey won't accept my password from time to time I have to change it and now I can't enter these sights.How can a Seller allow you to control their customers and refuse access when their is a password problem. With no phone number to contact you. I do intend to contact these various sellers to inform them that their merchandise is being controlled by who can see it and who can't and your site is not helpful to change a password. I remain unable to continue my shopping because of your total lacking in customer service.
