Meta description showing reg 123

Hi

I recently launched a new site for a client. It is ranking well on google already.

But when you search google for the following:

Fish spa bournemouth
or
Fish pedicure bournemouth

it up at the top but is showing

yutangspa.co.uk. Internet made easy. 123-reg has registered this domain for one of its customers. If it’s your domain name, you can manage it by logging in.

Not the meta description that I have set up. How do I change this or do I need to speak to reg 123?

Thanks

Tom
