Did noy receive what was agreed upon in the contract.

Selldirect contacted me on the 15th of Aug for the upgrade of my Telkom mobile contract. The contract contains the following HUAWEI P8 LITE 2017 + 100ANMins+10GBTMDatax3mths on FreeMe 1GB @ R199.I received my new device on the 21st. The new package was activated on the 25th of Aug. The 10GB data was never loaded. I contacted Sell direct and they confirmed that the 10GB was included in the package which was loaded onto the Telkom mobile server. On the 4th of Sep I logged a case with Telkom mobile. They said it would take 72 working hours to resolve the case. That 72 hours ended on the 14th of Sep. I have been calling them every other day with no feedback.
