Telkom Breaches Cellphone Contract, regarding Telkom to Telkom unlimited calls

Hi

I took up a cellphone contract with Telkom last November. in my contract. It states that Telkom to Telkom calls was unlimited and I will not be charged for it . Upon checking my balance this Monday which was the 06/08/2018, I noticed that a limit of 3000mins was put on for my Telkom to Telkom calls. I think Telkom has breached the original contract that I had taken up with them. If this issue is not resolved , legal action will follow.
