Best Virtual Assistant

We are looking to change our virtual assistant. Any recommendations. We are looking for a reliable team that answer the phone for us, answer emails and perhaps book keeping. The current team we have regularly drop the ball and we find we are constantly tidying up after them.

If you recommend someone could you please give us an idea of how long you have been with them, the reasons you love them and how they have helped your business.

Thanks in advance.

Cheers, Garry
