bad service/ where are my data bundles?

I bought WhatsApp data bundles on The 24th of October which never worked called customer service and i was told there was a technical problem they are experiencing i will be refunded it's been four days and i still don't have my bundle refunded i instead was forced to buy more data bundles as i had matters to attend to yesterday MTN customer service only created a ticket was told to wait 24 hours as if i haven't already waited enough this is pathetic im changing networks
