Terrible service

Terrible service. My contract comes to an end in a months time. I phoned at 13:00 today. The lady on the phone refuse to cancel my contract. After asking her so nicely 6 times, she still refused to cancel it and then put the phone down on me. I cannot believe that I received such terrible service from Vodacom. Vodacom, please let me know what you are going to to do to this lady, because if you are not, i will. I promise you I will be going to the press. So dont just sort this out, tell me that you are going to take steps against her.
