Vodacom not interested in new contract applications??

I app**** for a new cell phone contract online and received an email soon after saying that an agent would contact me within 24 hours. When no-one contacted me after 48 hours, I app**** for the same phone contract again online, received the same email confirmation of my application, but still no-one from Vodacom has contacted me more than a week since I did the second application. Is Vodacom so oversubscribed that they are not interested in taking on any new contracts? What must one do to apply for a new contract??
