Have you consulted Support for this service? It's expensive it should have Premium Support that fixes the problem or you shouldn't get charged.
Did you try each troubleshooting step in each tutorial I linked? There were dozens yet no feedback or questions about a single step. Please do not skip any steps. We often find out later that the fix was the skipped step. If you need help performing any step I will help.
