Terrible aftee sales service!!!!!!

Today is 21 working days since I booked in my repair, the first time they replaced the battery was 8 days ago there was nothing wrong with my battery, but it was replaced, my camera was faulty so they sent it in for repairs I asked the sales person to check what is happening with the repair the reprort said awaiting parts, camera and battery replacement again, im fed up with this repair that's taking so long the phone is 6 mouths old and a repair that takes longer then then 21 days needs to be replaced, refunded or given store credit. If i don't pay for my phone Vodacom will cry but if i need a repair then they can take there sweet time witch is against the consumer rights act. Worst warranty service of all time.
