Vodacom Business - poor customer service

Vodacom Business. No notification or communication of our contract coming to an end. No calls to even renew contract like they use to do in the past years. Just an instant jump from discounted monthly rate to a payment 4 x the usual amount. Sent by automated statement which doesn't help during middle December showing new debit order from R415 to R1625 processed for December , without chance to change or renew. I sent a request for immediate cancellation on that ridiculous amount . Wont be doing business ever again with Vodacom. They just silent money grabbers. Who keeps tabs on their contract count down. It doesnt even show on your invoices or statements how many months you have left on 24m contracts .
