We do reply to every email, so please check your spam folder. If you are using "Mail for Windows 10" please check your return email address. By default 'Mail for Windows 10' creates the return address something like this: outlook_abt81b5bb56a924e@outlook.com, which is non deliverable and no one can reply to. Please see the microsoft 'fix' for this 3 year old bug. Then re-send your email to us.
