Hey everyone, I just tried to get support and they replied the following
In order to assist you keep in mind that the promotion you have acquired is valid only for Colombian residents, and it is forbidden to use VPN in order to purchase this promotion.
Before assisting you please send us proof of Colombian residence such ID, home services invoice , driver's license etc.
Once you can proof that you reside in Colombia we can continue with the process, otherwise you service may be suspended during the following days.
Best regards

So if you do not proof you are a Colombian resident they will suspend your services, even if you use VPN. So better not keep trying to register domains there, anyways you can purchase the domain for less that 3 dollars with no restriction on their website. This promotion looks like is only valid for Colombian residents due to Covid 19 and they found that foreigns were abusing the service
