Don't buy phones from TFG / Hi stores

I am so annoyed, I sent a message to your Hi Facebook store yesterday, they told me to go into the store, now the sales consultant wants me to book the phone in which will take 7 days 😱 all my business stuff is on the phone how do I manage my business with no phone and for 7 days this is utter nonsense ... Phone is not more than 12 days old... It's freezing and I showed the sales consultant who also saw the fault, and it's making a system running noise. If it's doing this after 12 days what is it going to do next month, or a year....

So I trusted you to give me a 100% working phone and now this happens? And then I must put my business on hold for a week or more cause you want to try fix a brand new phone that I will be stuck with....
