NO NIGHT SURFER DATA ON CONTRACT!!

17 April 2015 we app**** for a contract deal which was 10GB 10GB night surfer data, including a 500MB ****le. Our 1st month was pro-rata and no night surfer data was received. Bill was paid on 15th May including pro-rata and new fee. Again no night surfer data. Queried it with Telkom store on 9/5 and to date no answer... Have been to back to the store 2 twice and each time was told the manager is still waiting for feedback. Why are we paying for this contract if we are not receiving what we signed up for and we are not getting ANY FEEDBACK. THIS IS NOT SERVICE!!! Please can someone resolve this damn matter now, this is becoming a joke!
