MTN has handed me over to the legal, for the usages I didn’t receive

MTN has handed me over to the legal, for the usages I didn’t receive. I have been taken from pillar to post, I contacted Mondo, they told me to contact MTN’s ***** department, which I did, however Nolwazi told me to contact MTN sales team,which I did, however they referred me back to Mondo. No one is willing to help me with clearing my name.
