Thanks
They're fake. Bitcoin has no "Helpline", as there is no "bitcoin" entity. If you want to know something, google it &/or use Bitcoin Stackexchange/Bitcointalk/et al. Otherwise you can contact certain companies that offer help, but those aren't the ones that "own" BTC so to speak. Be wary of giving sensitive info out though, especially if it's a relatively unknown company.
There is no such thing as bitcoin franchise unless it is coming from a company or business that appropriated the name bitcoin and add it to their existing name. As bitcoin is a decentralized platform, there is no official entity or group of people behind it just like what we can see in companies like Visa, MasterCard, JP Morgan or similar platforms. We have to be careful because there are so many creative people who can disguise pretending to be representing this and that but are actually just scammers all ready to punch anyone just new to this industry.
