FNB unhelpful

Seems like FNB doesn't like to assist their customers. I can't even upgrade my account with FNB due to "False" reporting by Vodacom to TransUnion. I am not asking for a credit limit or any of that, I just want to upgrade my account. But nobody can help, they can't even stick to their call back scheduled time. Everything is such a pain! I have all information to show that this TransUnion Vodacom debt is incorrect, I can pay it but why should I pay for something due to a company **********ly adding me to TransUnion for debt I am not entitled to pay. I have FNB law on call and will take this up, however, I need my account upgraded NOW, not 2 months time when this issue is hopefully concluded.
