Everything Bitdefender not working.

Renewed Bitdefender 2019 around 3 months ago and plus VPN all for a 1yr subscription and now all are saying I have to renew them again. All functions of Bitdefender (Firewall, Antivirus/Malware , Online security, Bitdefender Central) non-functional left me wide open to potential attacks, tried to run Windows Firewall couldn't had to completely uninstall Bitdefender to get Windows Firewall running (having to restart OS several time to do so) so I'd at least have a firewall up and running , the same for Windows Defender. Tried support nothing no reply so now trying here to see if I can get some answers to what's going on is there anyone of official capacity on here to help or for answers?
