Account has been handed over that doesn’t exist

My account has been handed over to your collection agency, which I find to be very odd as this account has been transferred to my husbands business account on the 11 March 2019.

I am struggling to sort out this account as I have been trying to get hold of someone in the legal department as every time I enter my ID number on the voice prompts it says it’s not valid? Then I phone the collection department that advises that the number isn’t in arrears which makes sense cause the debit order goes off monthly on the business account? When I speak to customer service they advise I need to speak to collections and collections advises I need to speak to customer service who is responsible for billing, it is an endless and very frustrating process.

Please can someone sort out this account or contact me as I am at my wits end with Vodacom really not sure what to do anymore.

A very frustrated customer
