Review Best Honey Sucker & Liquid Waste in Harare

I engaged HoneySucker & Liquid Waste Services to empty my septic tank. They picked up their phone quickly and talked to a gentleman who was very polite and helpful. I gave them the job.
They came exactly on the time agreed. Their technicians introduced themselves and did their job. Their job was thorough and my septic tank was finished. They showed me (though I did not like the sight inside the septic tank. Surely they had done a thorough job. They also did not leave some messy lying around.
This is the reason I have absolutely gave them a 5 star rating.
