Is langtoninfo.com Safe?

One month past after transaction, no goods no communication received. After escalation with paypal, received this email: I'm Edward from Langton Info writing regarding your recent purchase from us. I hope you were satisfied with your order and it has now arrived. Should you have any outstanding issues please respond to this email. We've introduced a rating system for transactions, so that other customers can evaluate our customer service quality. You can help by rating your order -- It's easy, just click the "Leave feedback" link below. Your feedback would be much appreciated. We hope to be of service again soon. Bloody ignorant attitude!!! Stay away from this crap shop! Existing on website positive feedbacks inconsistent and suspiciously monotonous!
