Telkom/Telkom Mobile confusion

<p>I bought R150 airtime at Lydenburg Shoprite. I asked for telkom mobile airtime. I was given telkom landline airtime. As we all know airtime is not refundable. I didn't know there was a difference. I call telkom customer care and they say its my loss. I believe that since the money went into their account they should convert or refund me. I don't know anyone who uses prepaid landline. </p>
