I would like to hereby formally request the removal of all my personal and private details from your company database as soon as possible.
I have recently noticed an increased amount of junk mail as well as telephone calls from companies that I have never been in touch within the past which are very disruptive and intrusive.
In order to avoid this from continuing, I prefer to have my details removed completely from your database as perhaps (name of company) has passed my details to a third party marketing company recently. Please confirm to me in writing that this has been done.
