SWAPPED NEW PHONES FOR OLD ONES

I recently took out two contracts with Telkom mobile & found that both the phones battery life didn't last long enough, please note that both theses phones where brand new, I then decided to visit the Telkom store at gateway and was told I need to book my phones in for repairs. So I did that. The problem is when both the phones came back they were not my phones, they have scratches on them & the battery still dies. Im am totally ****ed off, as my phones where new phones and in good condition. I purchased screen protectors for my phone and these phones came back without them. My point being if they could not fix the problem, why did they not just give me new phones & not someone's else's s****. To top it all, the phone came back with someone else's personal stuff on it, which means that I can access all his accounts, now Telkom can be sued for this. This is just utter ******** that the people at Telkom just don't seem to be doing their jobs.It seems to me that the guys just received my phone & swapped it with whatever **** they could find. The staff at gateway is *********** & when you speak to them, they look at you dumbstruck. Really is this the kind of service we pay for?
