Best fibre if you a masochist

My friends at vodacom tell me I was paying a ghost all this time. They have 0 record of my account being active. They vaguely tell me I stole the router somehow even though it was used and cancelled because of moving houses. they refuse to unlock a simple router. By the way every call they keep asking for different details which shows this is the reason I keep getting spam ams and calls, if they can't manage their own database clearly they are leaking or selling information. They must come collect their ewaste since I can't even use the router if they dont unlock it
