Hold on until your airtime runs out

Trying to call the call centre is a nightmare! Between my husband and I we've gone through over R100 airtime today and have yet to speak to a human being! The app is pathetic so you have to call. Most places at least offer an option for a call back! Not Discovery! No, for them it's "Please continue to hold!" Now just to sit and wait for their one-size-fits-all response to this review. Thanks for nothing, Discovery!
