kurio kids tablet

I bought a kurio tablet worth R2000 for my 7yr old child in Dec 2014. 3 months later it started having charging problems. I called the kurio helpline and was told to take it to a branch. That was done on the 24 May. Up to Mon 16th June I still hadn't heard from anyone. I called the helpline again and was told the problem is due to the charger not being put in correctly. I explained that my child is not allowed to use electrical cords so the charging has always been done by me, I've had 2 tablets of my own for a long time, I can't NOT know how to use a charger so how can it be my fault? The consultant took my e-mail address and was going to send me the 'technical report'. Told her I would also like for someone to CALL and explain the contents of the report to me. I'm still waiting! Toys r Us what am I supposed to do now? Why to you have suppliers like this and why is it my duty to follow up with your suppliers when you are the ones selling to us? R2000 is a LOT of money to pay and have such problems 3mths down the line.
