SmartBroadband 100 not working for me :(

On the 28th of February 2018 I took out a SmartBroadband 100 contract with Telkom Mobile which was a double data deal meaning I would receive 200GB Anytime data + 200GB Night Surfer. I also added a MultiSim that I would use when commuting. It has been over 3 weeks and my MultiSim does not work and instead of getting double the data I am getting 100Gb Anytime & Night Surfer data. I called Telkom mobile & went back to the store more than once and yet I am not getting the package I signed up for. On the 13th of March a case was logged with the following case number: ********** 6 but up until today nothing has been communicated but my account was billed fully including paying for a MultiSim that hasn’t been working for over 3 weeks now. I am not very happy with the service that I have been receiving from Telkom Mobile because I signed up for a contract with them knowing that they are a reputable company. This is a huge inconvenience because I have been going to the store back & forth, yet nothing has been done. Telkom Mobile will not make up for the time I lost trying to get this issue sorted.
