I've tried all the ways I know, dork, google dork, sqli dumper, havij and never got, no card number and in that there is an acquaintance that always has, there I buy from him, and he does not teach how he gets the data from card, can anyone help me? I can not afford to spend money buying cc info anymore

If we're talking about collecting fresh CCs in bulk, then your most realistic route is to hack into an ecommerce shop/service and passively collect plain-text CC information through the use of form-grabbing scripts. Alternatively, you could employ email phishing to promote replica landing pages or specialized malwares. There are other methods, of course, but this is just to give you a simple idea of the route you'd need to take.
Good luck.
