Hi richard999
Thanks for your post and welcome to our community.
We're very sorry to hear your installation has been delayed, we can fully appreciate any upset caused by this. I'm afraid we wouldn't have the details on why this has been rescheduled from here, but we can assure you we wouldn't cause any delays unless they were necessary.
Once any necessary works are completed, your installation will then be booked in for the first available date.
If you make contact with our pre-installation team on 0800 052 1734, they'll be able to investigate and assist you further. We hope that we're able to get you installed ASAP.
If you'd like us to raise a formal complaint for you, please let us know and we'll send you a private message.
This will be assigned to our installation complaints team who will then be in touch.
