Internet depleted

I have no internet. Spoke to the agent, was told my internet package has been depleted. Today is the 11 March, I had the same message in Feb, so I waited for the new month. This is a back-up package,not my main provider. I hardly ever use it. I was told to remove the sim-card from the wi-fi phone, put it in a cell phone and to dial a number that will indicate my usage or whether it is a technical fault from Telkom. The simcard does not fit into any of my cell phones. So here I am stranded , with no solution. Extremely frustrated to pay for a service that is non-existing. I once again ask myself: why am I still on the telkom network at all???
