Is an additional firewall needed for the download of Office Home and Business 2013?

[Windows Central Question]

I recently purchased a new laptop (HP Pavilion 360) and I attempted to install Office Home and Business 2013. An error sign appeared letting me know that the key I used had been accepted but I needed to phone an 1800 number to check what the error was. When I phoned the technician told me It wasn?t installing and that I needed to purchase a firewall to successfully complete the download of Office 2013.
Could you verify to me that this was the correct advice please? The firewall she sold me was from AlliedWallet and cost 250 US dollars. Have I been scammed?

In short, yes, this is a scam.

There is no relation between installing Office 2013 and purchasing a firewall.
