Hi @stellafiona and a warm welcome to the Community Forum. I am sorry to hear that you have not yet managed to secure a sit. The best way to get in touch is to email support@trustedhousesitters.com
If you are willing to give it another try, I would suggest that you also add your TrustedHousesitters profile on to your Forum profile on here by following the attached link. This will then enable others to offer you helpful advice and feedback to help you secure your first sit.
If you are unsure how to do this, or if you have any questions at all, do not hesitate to ask, we are all more than happy to help.
