Airtime Dilemma

<p style="color: #555555;">I purchased R 100 Telkom mobile airtime at one of the Woolies stores after buying it i went straight home only to find it was not Telkom mobile but Telekom for landlines. What do i do because i am sitting here with R100 worth of Ladline Airtime when I purchased airtime for my mobile. I called Telkom to seek ***istance they asked me to go back to the store I purchased the airtime. It strictly says on the Woolies slip that no exchange/refunds on Airtimes. Please Advice!!!</p>
