Waiting for a refund

<p>I have purchased airtime on my Wi-Fi simcard to convert it to data. This option was no longer available according to Vodacom.</p> <p>They advised that they will do a refund to my bank account. This was a request that I have submitted on the 26th of May. I have followed up again a week later and they advised that they are busy with the request. I have followed up again last week and they gave me the same feedback. Will you attend to this urgently? You cannot take more than a month to sort this out. Service request number - ********** 8401</p>
