Unfortunately, this entry is another one that you’re unlikely to be able to do anymore. Most companies will have a stipulation in their policy about the 30-day guarantee only working for new customers instead of those who previously held a contract. You can probably blame this guy for it not working anymore!

It’s quite a clever scam, and I’m honestly surprised he managed to get away with it for so long. Eight times means he got “free” Internet for almost 8 months – just under a year of WiFi without needing to pay a penny! So, it’s no surprise this scam doesn’t work anymore.
