Almost a month of waiting for Fibre

I placed an order with Supersonic for FTTH. after almost 2 weeks of zero communication from them regarding the progress of my order, I logged in one evening and proceeded to cancel the order.

I then got a new ISP (RSAWEB), who were super helpful and on the ball with the order and were prepared to have us up and running within 5 days. The very next day, after cancelling the Supersonic order, they e-mailed stating that Vumatel is requesting my FSAN so they can confirm the ONT. I then asked them why they are asking as I have already cancelled. RSAWEB then reverted saying they cannot proceed with installation as there is a pending installation for the same unit / ONT. I was furious because I already cancelled with Supersonic. I then thought I would give Supersonic one last try and accept that they asked for the FSAN since RSA declined. I emailed the guy who handled my order to request an order number with Vumatel (the order from Supersonic to Vuma) so that I can follow up with Vuma myself; the agent had an out of office, with someone else's email, whom I did email but still no response. I have lost ALL patience because today, RSAWEB would have been able to install for me. I do not want my current 5G to go another month and this is causing massive delays and costing because of the lack of communication and poor service received from Supersonic. I need a formal cancellation from Supersonic, if not I need an order number today still.
