Incorrect credit score nightmare.

No one capable of helping or transferring me to someone who can assist. As someone with a high credit score, zero debts and a very high annual income it's incredibly frustrating when vodacom continues to tell me they can't offer me a R99 contract because my credit score is low. No one is able to tell me why or how they have this incorrect information let alone how to fix it. Every mode of communication has been exhausted. Email support promised to fix it but eventually stopped responding. In person help is useless as they offer only basic sales and tech support and refuse to even let me know who I need to speak to to fix this. Being constantly transferred from consultant to senior consultant to other departments via phone yields the same result. I understand an individual not being able to help me directly but no one putting me in touch with someone who can help is beyond incompetence in training.
