Poor attitude and service from NATIS call centre

I am having such a bad experience with Natis. Paid for 3 licenses, one month later have still not received them. Called their call centre, held the line for 20 minutes, then call centre agent was both dumb and deaf, kept talking over me, when I asked him to please be quiet so I can read him the reference number, he put the phone down. So annoying, rude and unprofessional
