If i live in mexico city, is this the same number? And do they charge anything? 
Also do they speak spanish?

Its a really bad idea to promise those kinds of things.

Although i have to aplaude your enthusiasm by doing adds and getting more people to notice you, your aproche was not the best.
You would get better results by just being honest to people. Say this is a greate buisnes oportunity safer than opening a shop and have it fail
but it IS HARD WORK, (nobody belives in making a lot of money by staring at the sealing, and they souldnt because you cant) but
the benefits can be great if you work hard every day you could in some what short periot of time (shorter than working a regular job) make 100k a month

Remember always tell the truth and give all the facts.
Dont create false statements because you just let people get disapointed and then they end up saying that GDI and all network marketing is Fraude
