Telkom Old trick never dies

Old trick never dies. I apply for a data SIM R59 and you get 15gigs which I only wanted for printing network. I notice my data get finished up fast after 2-3 of use. Tried *147# option to buy more gig sins I only want 1 gig because I am on the end of the month. This option failed not to my surprise. I called the Telkom Mobile Call Centre. Spoke to an Mobile agent and I explain problem and cant buy 1gig. I did this before and now nothing. Just want to get through the month for printing(3days). She said she going to adjust my limit to 1000. I just want to add a 1gig - no limit is the only way. I had to agree to get back to work. Call was done. Here is the problem: I started with asking for 1gig and I need to get thought the month. It was not 1 hour when I saw a screen indicated out of data(just for printing). Next month Bill I see additional R1000 to my bill and R100. Log a Dispute where agent tells me a supervisor will call me. Still waiting. few things is wrong here, 1. Why did the data for R1000 got gone in 1 hour. 2. Why did I get bad advise from agent. 3. Why no Supervisor call me back. I paid R59 for a reason not to over spend on data due to I have Infinity cell data, now I pay R1100 for bad advise from Telkom. I want you out there to be very careful. They catch you like this. Old tricks never dies. Very Disappointed in Bad service.
