Hey Rlawton9292, thank you for reaching out.
Okay I have taken a look at our side and will need to speak to our Pre Installs team for this. I'm afraid we're unable to assist with installation appointment change requests from here.
They can be contacted on 0345 454 1111 they are open between 8AM- 9PM Monday - Friday or 8AM-6PM Saturday and Sunday.
Please let me know you get on. Thanks
Matt - Forum Team
