No follow up even though indicated they would

I posted a report on my engagement with Vodacom on my cell phone contract last Sunday, 6 March. I received a response within the hour of posting indicating that Vodacom acknowledges the report and a consultant will be intouch. I received an sms on 7March indicating a consultant will make contact in due course from Robin Morris. I have had no contact or feedback to date. What does in due course mean, a week , a month? A timeline for engagement would be appreciated to resolve the matter.
