Account paid NO connection for 3 months

My account has been paid up for 3 months. I cannot use my cell because MTN has not re-connected me. I've emailed Customercare, Re-connect manager. I've called but MTN never answer. I've asked the branch to contact MTN but am still not connected. Can MTN please re-connect me or tell me what the problem is.<br> I feel cheated as I've paid my bill for 3 months and cannot use my service.<br>
