How long should a Credit take?

I logged a request for credit on my account on 28/12/2014. Up to today (2/2/2015) this has not been passed.<br> The credit was for Data Charges while I was still within my monthly CAP. I've asked for a credit of just over R 2300. <br> <br> I'm unable to speak to anybody in the credit department to have this resolved, and need to hear the call center will escalate the call via Email. I'm tired of this and need this resolved.<br> <br> Leading on on this I will not be renewing any on my contracts with Autopage after they expire due to this instant.<br>
