Bad service

On the 23rd Dec 2015 @ 21h18 I bought one of the Telkom Mobile Summer data bundles deals worth 500mb that expires after 1 day. By 00:06am (24th Dec 2015) I got a message that says my 400+mb remaining data has depleted. Surely in a day there's 24hours, I was shocked to see that the 1 day data expired within 3 hours. <br> I immediately lodged a complaint via Twitter and @TelkomZA admin has been making empty promises about solving the issue since that day. Even now I haven't had any feedback from Telkom mobile except that my query is being investigated. I don't know how long such an investigation should go on but I believe that 15 days is a long time. <br> I'm very disappointed with Telkom mobile.
