nonconforming product to my order

I ordered these cables Cat 6 SSTP (10 m. and 15 m.) to change mine (SFTP)
to optimize my connection.

At the reception there was SSTP well marked on the label but looking more closely at the cable,
that does not make the one who prepared the order,
SFTP is marked so it's not what I ordered.

Since these cables are identical to those I already own, it does serve me nothing.

I have spent several days on the net looking for SSTP and I end up with SFTP cables I own
therefore useless, yet wasted time and money to return these cables.

I think it is not serious dAmazon the part that does not check and seller who gives false indication.
