When I ask somebody is a product or anything is available, it says the messages is delivered but they never get back to me! Also when I put a post on nobody gets back to me either..... the problem started back when I put a house on (letgo) before they changed it to (OfferUp) after they changed the names over... (They blocked me)!!! They tell me when I have notifications on products that I want, but like I said when I try to respond NOTHING HAPPENS! I wish they would forgive mistakes!!!!
