Contract Line Incorrectly suspended

Good day

Please take note that my contract line has been incorrectly suspended, I called the customer care line yesterday afternoon and to my surprise I was told that my line was suspended, My account is paid in full to date and I am actually on a positive balance with MTN as I paid extra.

I request that this be resolved immediately, as this has caused me unnecessary inconvenience. I currently use this line for my children in case of an emergency and now they cannot even dial out due to negligence on MTN's side. Please resolve this urgently.
