Not sure if it is what you are looking for but Answer.co.uk is pretty good - they take messages and email it to you. If you set the email to your support team's inbox then your operators will be able to give the customer a call back, or even drop them an email in regards to their query.
I have used this in the past for other projects.

We've been using BobCares for years and are happy with them. They have a high level of service excellence.
Would recommend them to you.
