Vodacom Gateway need to get a huge wake up

Sent my phone for repairs at vodacom gateway repair centre, I phoned like a 100 times to see if it's ready,there is no answer, so I decided to go to the store they asked me if I accepted the quote, when they never gave me a quote. I accepted the quote then. After a few days they send an sms that the phone is ready for collection. I go to the store and they don't have a battery for the phone, I waited for like 20 minutes and then they tell they putting a second hand battery on the phone and they will post a new battery to me, now that I have the phone it doesn't work properly and when I'm trying to phone and complain to them there is no answer and the battery that they had promised still haven't arrived as yet
