Confused at how tfg can provide such poor service

I purchased a connex tablet from foschini in galleria a few months back. The tab has just suddenly stopped working, it is still under warranty.

When i went to the foschini store i was told that the lady that handles the returns is not in and she will contact me today 20.01.21. The lady did contact me however she told me that the stores phone lines are down for.2weeks.now and she is not sure when it will be back online. Therefore she cannot log this return indefinatly.

So my question is what must i do now? I dont have a tablet which i purchased soley for the reason that i need it for daily use and secondly how does this become my problem that the store is unable to do what their supposed to do?

I dont blame the staff as their obviosly dont have the resources but can no one assist.surely foschini makes enough money to buy a mobile router and some data in the interim.

I am extremely disatisfied with this service and cannot beleive the tfg can be so ridiculous. I urgently require a replacement tablet or a refund as i didnt pay for a tablet that lasts a few months.
