Legal department won't clear me after paying my account

I had an account with MTN, due to financial problems I count pay my account so they referred my account to MTN legal department. Legal department called me, and I payed my account. Earlier this month I went to branch to buy a phone and the consultant told me that we can not proceed with the application because the status says I am still with legal department. I told the consultant that the account was paid in full. The consultant send an email to legal department, to clear my name even now I'm still waiting for feedback
