Unusable Data Code

I bought R180 telkom mobile data on the 31st May 2015 and received a code that couldnt be processed. I called telkom mobile call centre and they offered to help with a recharge if I could provide them with a serial number. I called the OTA call centre on monday the 1st of June and no help provided instead i was promised that the admin dept will call me back. I called again on the 2nd to be given a reference number by a stupid call centre agent who kept on wasting my time by asking the same question for 10 minutes. In a ****y voice, he also promised me that the admin dept will call me back and still no one called and today is the 3rd going to the 4th nothing happend. I want my data or I take this matter further with your ombudsman.
