*********** sales consultant!!!

Hi,so on the 13/01/2021 a sales lady calls me offering a new 24 month data contract for R99 a month.I gladly accepted to sign up telephonically previously having something similar to this,on 16/01/2021 I try to make a voice call suddenly I get an automated message from cell c saying I am unable to do so? After calling the call centre and a Twitter response from cell c I'm being told it is now impossible to have the data contract plus use the sim to make voice calls???

Previously I had a very similar 24 month contract and a limit increase, receiving my data every month plus being able to make voice calls to my limit increase usage?? It's either cell c resolves this issue or can cancel the contract and reconsider porting to another ISP !!
