It has been an absolute nightmare trying to get into contact with the customer service at I-to-I. I completed my level 5 course, after having to spend even more money because I wanted to LESSEN the amount of hours for my completion. So after I sent more money, the adjustment was made and I was sent a congratulatory email with with several links to click and view the certificate. And guess what? Neither link works with the candidate number they have given me. Turnaround time for a response to an email is at least three days. I try to call and never get an answer. And now I'm guessing that they'll require me to pay even more to have a printed certificate sent because for some reason the pdf won't work.
