Utterly disgusted in poor after sales service Vodacom Canal Walk repair centre

I took my phone in about a week ago and was told the phone was liquid damaged... when I had to query a full week as no one got back to me even the store manager was too busy. Collected the phone today and the phone is now not working. The phone was in working order when I booked it in and I now have a completely broken phone and they just said it's because if the camera that was liquid damaged. The phone was fine before I took it in... utterly disgusted.
