Unprofessional behavior

I was offered a 24 month contract with Telkom by their marketing department called Sell direct. I requested to keep my prepaid number and they agreed. After activation I received an sms informing me of my new number. When I called them to query the mistake i spoke to Jasmin Samsodien. At first she was helpfull, things changed when I requested to speak to her superior as i could not get anything concrete from her. She refused to call her superiors siting that they are busy in a meeting, when i persisted she promised to go and call them but never came back.
