Thanks for your question. My name is ***** ***** I look forward to assisting you.
It looks like an alert has been created on your Gmail account
Click on my link below and check for thishttps://www.google.com/alerts
remove any alerts and this should then stop you receiving this.
If you do not see any alerts there, then it is going to be in your calendar.
Sign into your Gmail calendar via www.gmail.com
Then click on Calendar in the top right.
Go to May 18th and remove any events listed there
I can also do these steps for you, and have made a request via Additional Services. This is optional, and if you choose to do this, I can, with your permission, remote into your computer while you watch and do all these steps (and deal with any problems that arise during them) for you. Or if you do not choose to take this service, we can continue here. This is no problem at all. Just let me know please.
Let me know the results please
