Unfulfilled promise

<p>Good day,</p> <p> </p> <p>I would like to express my disappointment in MTN South Africa, where they offered me free 500MB of data and as a result they gave me an invalid voucher pin. This comes after I retweeted their promotion on Twitter and as a thank you, they gave me free 500MB. However, I have expressed my invonvience by contacting them on twitter and they have promised to resolve the issue since the 18th of November. Still to this date, I havent received any communication eventhough I offered them my contact details.</p> <p> </p> <p>I am much unhappier with how they have handled the issue. I hope hellopeter can assist in sorting the matter.</p> <p> </p> <p>Kind Regards,</p> <p> </p> <p>Twitter:SimplyDope</p>
