Bad service from VOX Telecoms

I am very much disappointed with their services as I want to enrol for fibre on them but their subcontractor (ES TELECOMS) keeps on postponing the date to come and install. It’s been a week now, everyday I receive an email and calls of informing that they are coming while I need the internet connection as if NOW. They should rather just keep their service and will check another competitor who will come as of TODAY.
