Account handed over

My data contract was **********ly upgraded through a vodacom store. I was asked to get an affidavit and log a query with Vodacom which i did last year in April. I have followed countless times with Vodacom to get the status of the query and my account. Since the upgrade happened i have not been receiving any data as my sim no longer works. My payment arrangement with Vodacom is via debit order and they have not been debiting me, which was not a surprise to me as i have not been getting any service.

To my surprise today i get a call from some law firm saying that my Vodacom account has been handed over to them for collection. I go and check my credit score and indeed it has been negatively impacted.

Very bad service from a service provider i have used for so many years and never missed a payment with.
