Telkom lies, can't make calls

I've got a SIM only deal with telkom and on Monday 8 August 2022 I got a call from one of the agents saying that I qualify for the upgrade from 40GB to 120GB, "why not?"

I explained that I need to be able to make calls as I currently do and still have my data that I use, "why yessir, nothing changes except the increase in data for ONLY R249...", as I'm writing this I came from the telkom centre in Sandton city as you can't get any help from telkom online as their site give you **** journeys that lead nowhere...

I can't make calls as they upgraded and renewed my contract without honesty and I'll need to recharge if I'd like to make calls.

this is not on for me and I need to make calls as I was able to on the 40GB without having to recharge.
