Desperate for an answer

I'm experiencing some issues at the moment. One of the sim cards which is part of my Smart Home Premium Bundle has been suspended (stopped working about a week ago).<br> <br> Over the past two days I have racked up about 3 hours on the phone to Telkom to understand why this was done and how to get it resolved (the other three sims are still active).<br> <br> I have now established a loop whereby I get transferred to and between accounts, mixed line department, business mobile department and sales department and regardless of who I speak to or where I start I always end up at the first department and no one has been able to assist me.<br> <br> All I want to establish is why the number has been suspended and how to resolve it.<br>
