Law / Where can I check in Poland my company formation status and tax number NIP and REGON? [95]

Hello, everybody!
Who can help me find out if a company from Poland is active or not? I am from Romania and I want to import from SESA POLSKA SP Z O O.

I have checked in the link above the KRS number, it seems to be ok, but the site is not in English and I don't know if the company is still active, with all the financial reports active...

Anybody, a little help for me?
I found so many scammers on the internet, that it seems almost impossible to be sure of the reliability of a company....
I am supposed to pay an advance (about 5000 $) and I don't know if I should take the risk...
How could I know that the bank account belongs to the company, and not to some scammer who uses the name of the company in order to cheat clients like me?

Thank everybody in advance!!!!

I want to import A4 copy paper. Any idea?

I've noticed there's only one mobile tel number, but I checked the VAT, KRS and NIP numbers.... everything looks ok! Even the address and the contact person found on the internet are the same as in my correspondence.

In my opinion, the only problem could be the bank account! I have to check if the owner of the account is this company or some person who just uses this company's name...

Thank you, Jon, for your answer!
In deed, as you said, I have two issues:
1. The company - is it real, is there a serious person managing it, the products that I want to import, are they for real?
Their site is newly founded. But, as I said before, the firm is listed in official polish documents - as you said, for example, Panorama firm (if I understand correct, the company cannot control this listing).

2. If this company turns to be a reliable one, the bank account they gave me, is the company's bank, for real? Or do I risk to transfer the money in a scammer's account?

Thank you, Jon! This is exactly what I was thinking to do - check their bank account, with my bank's help.
As for the company, I've contacted infotimes.pl
It costs me 25 Euro to check the company from A to Z.

I don't know what "nominated freight forwarder or TPI" means.
But infotimes.pl offered me this, for only 25 Euro. I think it is a detailed analysis.
