Whoever todl you that your site would be listed in two to three months was significantly incorrect, and I am confident that you were not given that advice in this forum, for any editor offering such advice would have ben pummeled into dust by his or her peers.
Our FAQ details the timelines, wich can exceed three years.
We do not give status checks any more, and there is a link to that announcement in my signature block.
that fact that you have not been listed is, in our view, not a problem, although from your view we can see how it might seem that way. The ODP is not a listing service for webmasters. We accept suggestions from non-editors, such as yourself, and we will probably, eventally, get to all such suggestions, but they are really only one (fairly poor) source of potential listings for us, and we do not heavily rely upon them in our directory building efforts.
Why, then do we accept suggestions if we are not willing to get on them right away? Good question. My personal opinion is that many editors would like to do away with suggestions entirely, but for the realization that once we closed off suggestions we would catch even more "what for" that we do now, because it is less damning to be wrongly perceived as slow and inefficient, than it is to be wrongly perceived as being unable to accept community input.
In any event, if you have submitted your site, that is really all that you can do. Suggestions don't expire, they don't get tossed into the recycle bin if we don't look at them in a given period of time, they just sit there, patiently waiting for an editor to show enough interest to take a peek.
You did say that your site is a usual online shop as alike thousands of others. I certainly hope that this is not the case, as we seek out unique content, and if your site is just the same as thousands of others, we would have little motivation in listing it. I hope that was simply verbal shorthand and not a true representation of your site. Oh my!
