Vodacom not looking good

Vodacom is really working on a person's nerves. I ordered a Adata power bank on the 29th of November and I still haven't received a confirmation sms or delivery of the power bank and its been nearly a week since the order. I've tried calling vodacom customer care and they redirected me to the after sales department from there i was once again transferred to the customer care department and they transferred me to the rewards department (well tried to but the call never went through) No one has the knowledge in 3 different departments to be able to assist me and every time I had to explain the situation more than 3 times because they could not understand the phrase "I made a purchase on the vodabucks store, never received a confirmation sms or delivery and its been a week"
