Sorry but how does one answer a private message from Verizon support. There's no reply link on them.
When you click on the subject line of the private message in the community forum, it opens the message itself. From there you should have a reply button. When you click on the reply button, it will open a text editor where you can write your reply.
Let us know if you have any additional questions.
I'm most definitely NOT a VZW employee. If a post answered your question, please mark it as the answer.
