Vodacom is ******ing me

<p>I have been a Vodacom contract customer for about 4 years. In August one of my phone's contract ended, all along my data and calls were capped but all of a sudden in July and August it was no longer capped and I had to pay R800. Last month I got an invoice of R1800 for a phone which it's contract ended in August, I called prior to August to cancel the contract. What amazes me is that for the past 23 months while on contract my data and calls were capped and I payed my normal amount but in the last month surprisingly it's no longer capped and I have to pay a ridiculous amount. No one is understanding my situation when I call the customer care. </p>
