Vodacom handed me over for debt collection when I haven't had a contract dor months?

Apparently I have been handed over for debt collection on my Vodacom number.

I am a prepaid customer who has not had a contract for over a year.

How can I be using my line as a prepaid customer if I have arrears?

Vodacom has not contacted me in any way whatsoever, sent me statements, arrears or anything as such.

I can only assume this is a ****.

I cannot get through to an agent phoning 082 135 AT ALL. I get redirected to Tobi all the time. Tobi can't put me through to an agent.

Phoning ***4 doesn't work either as I get a message that I'm a prepaid caller...

I have always had a debit order and Vodacom was free to settle any amounts outstanding.

Please can Vodacom urgently address this and remove me from wherever they sent my details to.

Note: I will be abroad and not taking calls for the next week. If Vodacom need to contact me, reach out to my on email.
