Telkom, where's my data?

Been a client of telkom for a couple of years now, but now I feel like canceling my contract. This year March, they had a special running, 80g daytime data and 80g nighttime data for R200 a month. I canceled my wifi, but when I saw this offer I couldn't resist . So I went and took out a contract again. Now let my tell you, not once have I received my full amount of data. I decided to go into their walmer park branch today. The lady who helped me, first tells me that she doesn't see such a contract on the system for me, wonder what I'm paying each month then, then she tells me, oky she sees that I have a 40/40 deal and not a 80/80. I again tell her this cant be rite. Then atlast she tells me oky she sees on the system that I do have a 80/80 contract. And that I am getting all my data. And that all my data wont show on the telkom app, because its a promotion. But each month the data that I cant see will start depleting first and then the data on the app that I can see. If that makes sense. I tell her but last month I ran out of data and on the 1st when I got my new data, immediately the data on my app,which is 40g day and 20g night by the way, started depleting. She rep**** well she doesn't know, she'll have to lock a call for me. So I signed a contract for 160g in total and I'm only receiving 60g in total. I am on the verge of canceling my contract with them. Very frustrated. I mean if I'm really getting all my data, why not display it on the app for me to monitor? I smell a rat.
