Worst service from telkom

I signed up for the promo smart broad band 40gbs which includes an extra 10 gbs day and 10 gbs night and I still haven't received the 10 day and 10 night and I signed up on the 04th of September 2020. When I go into the store that I signed up in(Gateway) they are all telling me that I didn't receive it because of pro rata which I thought was abit odd because its a deficit of 13 gbs so they referred me to support and spoke to Nomsa which In turn said I was on the wrong contract and they must change it in store. When I get to the store they say the contract is correct support doesn't know what they talking about. So I told them what is the way forward the lady I spoke to Xolile said they referring it to the back office and they will decide whether I should receive it or not and I was given a case number ***4. Till now I'm still waiting for a call or something from the back office. Can someone please contact me to let me know whats happening or yourl must deduct the deficit of the 10 gigs.
