terrible service with ***** case

In November last year i became another victim of cellphone ***** at Vodacom. Went to a store in pietermaritzburg to log a case in December however nothing was done. only for my account to be debited with over R1200 in DEC 2018 when i do not even have a contract with vodacom upto today their service agents have given me a run around and i still dont have a case number for the ***** claim. my next step i guess should be opening a legal case against them.
