No refund on data bought on SIMcard

I bought data for an MTN ****le with two transactions on 17 and 18 May, but still could not gain internet access. The total amount bought through myPrepaid was R989, and it went off my bank account. I visited the MTN branch in Herm****, but was told that no data was loaded onto that ****le on Simcard telephone number ***. I was advised to speak to the bank. I did that, but Absa informed me that only MTN could refund me and that I should again approach MTN. I visited MTN Somerset West yesterday, but they also told me that I was to speak to the bank. Below is an excerpt from my bank account, showing details of the transactions. <br> <br> 2015-05-17 IBANK BETALING NA VEREFFEN<br> ABSA BANK Mtn ****le Data -600.00<br> 2015-05-18 IBANK BETALING NA VEREFFEN<br> ABSA BANK Mtn ****le Data -389.00<br> <br> I also phoned the MTN Customer Services Helpline, was asked to stay on the line. I held the line for for almost an hour, and tried again, with the same result. <br> I need the amount of R989 to be refunded, and hope you can help me. <br> <br> Regards<br> <br> T.Papenfus<br>
