Vodacom is a **** and care less on responding on ***** case

I used to have a contract with Vodacom which I terminated in Mar 2016. To my surprise on the 21st Jul 2023 boom debit order. When I went to Vodacom 4u Clearwater to find out what happened, there was a cellphone contract taken using my personal details(ID no, name and bank account) and delivered in Durban . I asked to see the FICA documents uploaded for verification, there was none. I lodged the ***** case on the 23rd Jul which I received an automated reply with case number. No one has been in contact with me or no updates at all after sending numerous follow-up emails and their number is not working ,only an answering machine. Month-end there was another debit order and I checked my credit report the inquiry is there, that is affecting my credit score.
