Bad customer service

I recently moved into a new property, ordered a cancellation for my previous line and submitted a new order for the new property on the 22/03/2022. Moved into the new property and arranged a specific date for installation - the team was on site on 02/04/2022 and it was determined that the fibre can't be installed (no prior survey was done). It is now 06/06/2022 - 2 months later with no feedback and no fibre installation yet, each phone call to Vox has been unsuccessful, not a single returned phone call or even an e-mail. It seems that you are making too much money and don't want any new customers. I am really not impressed with how you guys are doing business and treating me as a customer. I am giving you 24 hours to get back to me, if not I am cancelling the "current" pending sale and moving to a different ISP!
