Still waiting on the manager call back

I called Monday as my prepaid Vodacom voucher gives an error message and does not want to load into my phone. The agent told me she is going to do network settings. I told her there is nothing wrong with my network settings and she need to transfer me to someone else. I then spoke to Leon the manager who told me he'll refresh my line then call me back. I'm still waiting for my call back and airtime still not loaded. I didn't expect that from you Vodacom, very disappointed
