No service

So I purchase earpods with my vodabucks on the vodacom app. I received it on ***7 , one ear piece is not working. I notified vodacom on fb messenger about the problem and told it was escalated. It is now ***5 and still no contact. I'm sure I will be told about 7 day return policy and I notified you guys on the same day I received the item. Mind you it said "hisense" but this is definitely from the China shop
