How do I edit my listing so that interested buyers will see my phone number?

They said: At CarGurus we care about protecting your personal information and preventing malicious use of our private listings service. While we do allow sellers to share their phone numbers with buyers who have submitted an inquiry, our policy is that every first interaction between buyer and seller should happen on the messaging platform. As such, we do not allow sellers to include their private numbers or email addresses in the listing description.

I understand that but again my problem with your sight is it wont let me answer even when reply to them wont go through hence I miss out on a buyer as they think I don't answer them HELP
