LC*** , FNB Law

I have asked FNB Law for help with my MTN contract that I have a dispute with. FNB said I'm entitled to the contract that MTN is withholding. After I emailed all the paperwork to them, they said I can ask the NCC for help. This is a basic contract dispute, but FNB are not willing to do anything for the Plan I'm paying for. I need the contact to resolve this matter, MTN is denying me access and FNB is leaving it at that.
