Can’t upgrade to pay for a Professional Certificate programvor 1 Jahr, 8 Monaten | 7 Replies
Hi everyone, I’m trying to Upgrade to get the course certificate, I had to audit all the videos and the remaining part is the final quiz. I tried to perform the payment with Chrome and Firefox, with the PC and with the smartphone, I tried also different cards, like 10 different cards.
How can I perform the payment?
Maybe I have something wrong in the configuration o my account? I don’t know.
Please help me 🙂
