Very disappointing

Fibre ninja has a complete chaos of a system. Firstly starting from installation, from being handed over to 2 companies linteg fibre and another service provider they seem to be the ones handing the billing and oh what a mess. I paid my account in advance just to be called by Linteg Fibre to confirm a cancellation of my service that was submitted by Fibre ninja as they reported I didn't pay my account the last three months, AFTER THEY sent me a statement confirming the money reflected for a payment of 3 months in advance. On top of that today I get a sms to pay R100 which makes no sense as I paid my account two weeks in advance and my invoice stated I only owed R675 which I paid and now they are threatening to cut my line. Really a horrible service provider that seems to have no handle over their accounts reporting. Whoever works in their finance and admin department is lousy.
