[Plugin: Contact Form 7] Counting Submissions and Displaying total Number after Clicking Submit Butt

hi! I am looking for solution to my requirement that I want to count submissions via Contact form 7. I want total number of submissions (with custom wordings – such as “Your customer Number is –counted number e.g. 101”) on the page that would display after submission.
I want this counting number to be sent to my email also along with form information. Like: Name: email: etc. + Customer number (Counted Number e.g. 101).
Help me in this regard.
