Poor customer service.

I recently moved properties and had to create a new account with Vox. They were quick to send me confirmation on email that the fibre is installed and ready despite not a single person coming to do or test any installation. They quickly also sent me a pro rated invoice despite me having no service. I have sent over 10 emails and made 15 calls and yet not a single response. I am still waiting for my installation to be completed and my service to be up and running. Really disappointed at the poor service and non responsiveness. If the debit order goes off my account at the end of Feb without me having service I will be forced to get my bank to reverse it. Vox please can you urgently assist as my emails and calls clearly are not being heard.
