How do I get a letter/statement proving that I don't work for the same employer anymore?

I used to have 2 jobs. In September last year I stopped working in one of them. It was the Marriott. Now I need a letter or statement proving that I am no longer employed with Marriott since the date I stopped working there. I called 4myhr number and they told me they cannot give me that prove. So is there any other way for me to prove that I haven't been employed with them since September last year?|||You're asking them for the wrong information. Instead of asking for something saying that you do not work there, you need to ask for something that shows the dates you actually did work there.
