Fast VPN - Not truly unlimited - false advertising

Have configured my Fast VPN on my home router and was working great till a few times my main IP was exposed. I found out that my password was being rotated without notification from Namecheap.

Upon further investigation and speaking with one of their techs, there is a limit and it's 1TB then they start to rotate your password and don't tell you so then your VPN stops working, despite their advertising "Unlimited bandwidth" which is a complete and total lie on their main Fast VPN listing page.

Really disappointed with this one Namecheap, "Unfortunately, 1TB/month exceeds the regular bandwidth amount for personal usage and may not be supported."

First time I've ever truly been let down by false advertising in a product.
