Greetings,

We're glad to look into this & help you.
Initially, please clarify how you access your mailbox. Is it through browser or email client such as Outlook, Thunderbird?
Also, please check whether the emails are actually triggered from your account (check the sender's email address carefully) & let us know.
Meanwhile, we'd suggest you to change your email account password once as a preacautionary measure.

Thank you for your understanding in advance!

I will  try this tomorrow when and before I go to WORK.
your method of communication sucks. No reply emails are useless!
I need security now. I have sensitive emails to send in the next 2 days.
I wonder now wither I should have bought my security from you.
Getting very frustrated and angry with service!
