Silent Rain

Generally, I am very happy with Rain's service. But over the past couple of days it's just been mediocre, to say the least. Since the beginning I was using the R250 package, which I upgraded a couple of weeks ago, to the R479 one they offer. When I received my bill on the first of the month, I was owing close to R2 000. I made an inquiry as to what had happened, and I was told to wait a few hours for the issue to be resolved. Now the internet has been suspended. I have received ZERO feedback from Rain. I called in again today, and the poor lady who answered my call didn't even know what to do to help because the billing department, which is apparently the only one that can help, is just mum about this whole situation. So what now? And I am definitely not paying for all the the days I have had no service for.
