Absolutely zero communication on lie repair after paying

I'm posting here because I'm at a loss for how to get any help from this company.

My fibre line broke- no idea why, it just snapped. They sent people out, they said it needs re-installation. I say that's fine. I will get an invoice later that day.

The next day, I get hold of Axxess because no invoice is received. I receive an invoice and pay it immediately.

That was 6 days ago. I've been messaging multiple times a day, and the person I was in correspondance with has just ghosted me entirely.

Agents say they "have no feedback". I've paid my money, and even if installation wasn't immediate, it is common courtesy to acknowledge receipt of funds.

The agents now say the funds have been received, but now I'm just getting the "no update yet" response once again.

This is costing me and my business dearly, and after a week with no internet, I'm going to have to pay another provider to do this company's job.
