7 Day in Store Exchange Promise not kept?

For the last 3 upgrades of my wives phone we always went to Cell C Canal Walk.<br> As so far we hd a good experience with them. So much so that my mother also uses them for her contract.<br> <br> Last week Thursday we did an upgrade through them again for a Samsung J5 phone.<br> <br> We were told in store to remember if the phone is broken or defective within the first 7 days.<br> It gets exchanged in store. After this period it goes to manufacturer to repair or replace.<br> This is a standard thing they give you. I actually believe at all providers.<br> <br> So on Tuesday Morning the phone alarm does not go off. We notice the phone is dead. We take it as the battery is flat. And press the on button. It goes on. Comes to first screen but you can swipe to unlock it refuses. If you keep pressing screen phone switches off. Clearly its faulty.<br> <br> I phone the shop at opening time and explain and ask if I can bring the phone back its faulty.<br> They say has to be sent away, can be 14 days. I say but I dont understand this is well within the 7 days so it should be sorted out in store.<br> <br> They say no it gets sent away to JHB. <br> So now the 7 day thing is a ****. Because before or after 7 days the same happens with the phone.
