Billing issues with Vodacom

Vodacom is adding additional fees to our bill and they can't explain it. We visited the Vincent shop on two occasions and was referred to call the legal call center only to find out they can't pick up the ID number on their system. Tried sending an email got the response that the account is not in arrears until I called 082 135 "your account is in arrears". We are not getting proper assistance from Vodacom nor are they to solve this issue. This is so frustrating all they want is your money.
