Missing Data after recharge

Good day,<br> <br> I don't know if its still a good day though. Last night I recharged with a gig of data. I then proceeded to check my balance right after the purchase... To my disgust 600MB of the Gig was missing - in less than a minute. I called the call centre - but the agent was abrupt and refused to assist.<br> <br> I need you to give back my data or credit my account.<br> <br> I am really annoyed with the service I received from the Call center agent - Olwethu ***.<br> <br> You guys think that you can treat paying loyal customers as you wish.<br> <br> That's how a lot of businesses fell - by refusing to listen to their customers. This is not the first incident and I am taking my business elsewhere - right after we sort this issue and i receive a damn good explanation or you refund me.<br>
