I have made several purchases from this seller and have had no problems. Recently, I made several purchases of 50 yahoo mails. Many of the emails that have been delivered to me do not exist, they have not been created. I have been contacting them by email for over 4 days and have been ignored every message. I have also contacted them by telegram and they read/open the messages but do not respond. Could you please take responsibility and solve the problem? order id 3686 only work 25/50 emails ... order 3698 and 3700 do no work ANY email, they just no don't exist
