Unhelpful and unwilling to try

The Vodacom business department is awful and unhelpful. We have recently taken on a building and we need the information to be updated so the debit order can go off the right account. Betty from the business department claims to be unable to assist me or to escalate the matter to someone could help, despite relevant information and documents being submitted. Very poor service and at the end of the day, the customer is the one who suffers.
