"We do a clear verification of all individuals that we count with us and we do not sell us, they select us because they beleave in us and they choose us"
Indeed. Tell us about the verification process please, and how you satisfy yourself that the people who buy grades are fit to hold them and do the things people with those grades do, such as teaching children.
And do please tell us what good these certificates of yours are, ie why we should come to you to get them. As far as I can tell you claim not to sell anything that the buyer does not aready have. That being the case, what is the point of buying them? Are you claiming that your certificates carry more weight than those issued by the people that actually graded the candidate in the first place?
To make this simple for you, could you just give a yes/no asnwer to the following:
1. Is it possible for a candidate to buy a certificate for a grade higher than the ones he can prove he has? Eg, if I have First Dan in Smak Mouf, can I buy Second Dan from you?
2. Can I buy a grade from you in an art you are not a recognised practitioner of? Eg, I can prove I hold First Dan in Smak Mouf, you've never even heard of it... can I buy a certificate for that grade from you?
3. Are these certificates held in high regard by governing bodies? Eg, if the International Ju-Jistsu Confederation (which I just made up) would't take me at First Dan even though I have legitiimate First Dans in two other styles, would a certificate from you change their minds?
4. Do you take reasonable steps to ensure that the people who buy rank from you can carry out the responsibilities of those ranks?
