Jumble Auction Nelspruit unreliable

Jumble Auction Whatsapp Group Nelspruit is very unreliable . Maritzka and Reon Prinsloo promised my daughter delivery of her items she paid for, as they conveniently "forgot" their arrangement with her when she was supposed to collect her items all the way in Nelspruit. They refuse to refund her and so far delivery has not been made as promised.
