No installation 3 weeks later

I have never experienced such incompetency! I app**** for WiFi installation on the 2nd March 2024 and to this day no installation has taken place, I had to call and inquire that's when I received a feeble apology that they had a backlog so they'll install on the 26th,come the 26th I waited all day & at 4:30pm I decided to call again, the agent took my numbers, promised to call the installers then will come back to me,she never did, on WhatsApp I was provided a link, how am I supposed to access the link without data?? then called the installer who said there was power outage, why did I have to call them before I could be informed of such?? The call centre ended up not responding to my call, I probably was flagged as they've run out of excuses. My business is 100% reliant on WiFi, so I haven't been able to work because of Ikeja.
