POOR CUSTOMER SERVICE AT VODACOM

My wife is struggling with Vodacom where they say she took a contract in which she had no knowledge of. She never took a contract with anyone but her Vodacom number was converted to a contract. She has been requesting assistance from Vodacom asking them to tell who did she took the contract with and they say they can't see on the system because it's bulk contract which involves other numbers.

At the moment she owes Vodacom an amount for a contract in which she never signed for. This is disgusting considering the fact that Vodacom is custodian of all their numbers on the network yet they can't assist. At th moment she can't use her number because of this issue in which this is the number she has been using for many years as a prepaid number.
