Broken MWEB operations

MWEB's operations are broken. We migrated from ADSL to Fibre. The Openserve installation has been completed for days now; ONT is working, router sees MWEB network but rest of internet is still inaccessible. Your system says Openserve still has to do the installation while it already has been completed. I phoned technical support number (I made triple sure it is the right number) just after 5pm to try resolve it, while they confirmed the previous day I could phone them until 8pm to sort out the activation, website says the same, but the IVR says they are closed. I even tried the app and whatsapp. THEY ARE NOT PROVIDING ANY SERVICE AFTER 5PM. Zero support and resolution. Worst experience from an ISP ever.
