Well the get back to me post, was more of a dig. About you having soo many people contacting you and cannot really be bothered. I see no difference in calling or replying. Since it sounds to me like a inconvenience to reply anyways. Calling also wouldn't have told everybody else the reasoning.
Out of all the GSG threads, this is the first time I ever heard of this. So this was very important information to disclose. And have you bothered bringing this up to GSG ? You still should have contacted customers to tell them this screw causes issues, we removed them because, we returned it to you.
