GoDaddy was one of the first ones to call attention to domain tasting, later referring to it as domain kiting:

If I, as an anonymous user, search for any of my domains on GoDaddy, I find that they'll offer to let me use their domain buy service to backorder them too, even for domains I've had since the 90's. Without any further evidence, it's impossible to tell whether you actually have a legitimate case (though a sample size of one is hardly statistically significant) or if you simply don't understand how domain registrations work.
