I didn't receive activation code to verify my phone number (+62) so that I can't login to Gitlab

Hi my manager sent me an invitation to sign up and I followed the steps. In the part of verifying my phone number, I didn’t receive any code sent to my phone number (+62 Indonesia). I have tried several times to resend (been trying to change the phone number, and even also trying to use smspool) but ended up my account has blocked. Could anyone help me? I have contacted the support desk, they said that my account will be active in 30 minutes, but it’s already past two hours and I still couldn’t access my account back.
