US Immigration from Ghana

I received my NVC letter with case and invoice numbers last week. I logged on to the CEAC successfully once. Since then i cant log on to make my payment again. What should I do pls?

How would you know if someone is married in a different country? I was recently the victim of a second marriage. He had a wife in South Africa and married me in Ghana. If she hadn t contacted me I would never have found out. How do you protect yourself from theses types of things? I hope I m asking this question in the right form. Thank you

Hello. Has anyone had their case expedited by the US embassy in Accra either before or during COVID-19? My case was sent to the embassy on 14th October (showed READY on CEAC) but I've still not heard anything from them. I've emailed them 3 times and I always get an automated response. I'm literally stuck now and don't know what the next steps are. Kindly share your experiences. TIA

"ATTENTION: The Embassy is now processing expired immigrant visas. If your immigrant visa was issued before April 23, 2020 and expired before you were able to immigrate to the United States, please email consularaccra@state.gov. Include your case number (beginning with ACC) and full name. Once your email is received, you will be contacted with next steps. Please note that while we are processing expired immigrant visas, the Embassy has not resumed routine visa appointments. If you have already contacted the embassy regarding your expired immigrant visa, you DO NOT need to send another email."

My expedite request was approved on 10/10/20 and CEAC showed Ready on 14/10/20. Yet I haven't received any email or notification from the embassy. How much longer do I need to wait? Could this be due to the embassy not resuming routine visa services? Anyone with a similar experience during this pandemic? TIA
