Bad Customer Service

I have had to deactivate my account with Rain because their router randomly stopped working. When I called them up they said I should pay for that even if it wasn’t my fault. I reactivated my account a month after, on July 28th, and was told to pay R1. I was under the impression that they deducted the money on the first of every month, as usual. I’m only finding out today that they didn’t take the money, and they are now double charging me. I just called in a couple of minutes ago, the representative hung up on me when I asked why didn’t they take the funds, after he told me it was prorated charges. It is unfair for them to not take the money when it’s there, only to double charge me a month later when I least expect it. Not to mention that I was so swamped last month I didn’t even notice that they didn’t charge me.
