Terrible Service From Collections Department

I've been trying to get my Vodacom account issue sorted out with the collections department, I lodged a call to get this resolved on the 12th January, the consultant told me the process will take 7 working days, then I called after those 7 days, the first consultant told me that they escalated it, it would take 2 hours, nothing. Called again, the consultant told me issue was no escalated and they would do it but it would take 24 hours, I wanted to speak to the manager, the consultant told me that they can't put my through, the manager will call me in an hour, this was at 11a.m., no one called. I called again at 1p.m., they still can't fix the issue and they told me the manager will call, waited till 4p.m., still the manager never call. Then I called again at 4p.m., they said that they can't put me through to the manager but she has escalated it. So there is no way to speak to the manager, I keep getting false promises but no fix. Really disappointed with Vodacom, really reconsidering taking a contract with you guys, will take my business elsewhere.
