Back button from Thank you page

Question

User has just completed a purchase of the insurance product and he has gotten a Thank you page.

Now he clicks browser's Back button. What is the best practice?

• block an back button action and stays on the Thank you page
• error page with explanation
• bring user to step 1 of buying the same insurance product
• bring user to home page of all insurance products available
• bring him at the website homepage

Answer 1

You provide the user with a page that asks him if he has some problems or made a mistake while purchasing, add a contact form which enables the user to address his issue, for example "wrong address" or "wrong phone number".

If i would have to choose from your options i would go with: - bring user to step 1 of buying the same insurance product
