No communication!!!

I had a confirmed booking with Vumatel to install my fibre line today. I was contacted as well as sent a confirmation email confirming my installation at 8:30am on Friday the 31st of July. At 9am I phone to find out whether the team is maybe running late and I get told that all installations in the area has been put on hold because of an upgrade that they are doing so they are currently not doing any installations. Nobody contacted me to advise me on this and from what I understand they don't even have an ETA of when they will be doing installations again. I had cancelled my LTE line on the premise that I will from today have a fibre line. so now I will have no fibre and no LTE and no clue when I will actually have fibre and all they can tell me at the call center is sorry mam we don't know why no one told you. Why then did they send me a confirmation mail if they knew they can't do installations. I am so annoyed with the lack of communication, especially since I require internet at all times as I work from home.
