Looking for a reliable broadband service in Abuja

I run a mid-size non profit and we rely heavily on the internet for our day to day task (who doesn’t anymore)

Last year I paid to pull a fibre optic line to my office from a provider and paid a monthly broadband internet service.

Its been very erratic, Internet is decent half the time, very slow sometimes and the interruptions are very frequent (when we have zero services).

I thought fibre will translate to as little disruptions as possible (99.9999%)

Now, I am moving office, I am looking for a more reliable broadband internet provider in Abuja. Help anyone?
