Airtime not loading

I bought an airtime bundle fro your website. The money went off but the airtime did not load.<br> When i called the called centre I am told i need to wait for up to 12hours to load.<br> <br> Why is there a 12 hour delay for something that i require use immediately.<br> <br> I was arrogantly told by the supervisor that this is listed on your terms and conditions. When i requested were on your T' C's this is, after being put on hold for the supervisor to find it I am then told its actually not on your terms and conditions but rather an internal process.<br> <br> Clearly your staff have no clue. Furthermore after kicking up a fuss, I am then told that this is an issue with clients not receiving airtime. <br> <br> The called centre agent was Shenay and Mishendree was the team leader
