Never changed my account

I phoned Vodacom on the 30th of November to downgrade my cellphone contract. I ask to downgrade to the Flexi 55. In December I thought ok I need to wait a month. It's now January and I'm still not downgraded. They had on the first call confirmed it had been done. On the second call on the 18th of December they promised to call me back as the system was down. Big surprise. No call back. <br> <br> I would liked this sorted out with out me having to call back and wait forever on the phone.
