<p style="color: #555555;">I bought a vodacom tablet, as part of the deal I was supposed to receive free R300 airtime.</p> <p style="color: #555555;"> </p> <p style="color: #555555;">On 25 December I called called vodacom to enquire about the airtime as I hadn't received it.the agent I spoke to said I have to buy R29 airtime and wait two days to receive the airtime.I did that. Two days later still no airtime.</p> <p style="color: #555555;">I called vodacom again, they said I should SMS the word new to 31118 and wait another two days. Two days later still no airtime. </p> <p style="color: #555555;"> </p> <p style="color: #555555;">On my third call, the agent I spoke to said they would log a service request with their technical department. I received an SMS saying they would call or SMS me in 48 hours. </p> <p style="color: #555555;">48 hours I still received no feedback. I called again.spoke to a manager named Desmond. He promised to call me back. Still no call from him.</p> <p style="color: #555555;"> </p> <p style="color: #555555;">Basically vodacom keeps changing their stories and I still haven't received my airtime!</p>
