unfulfilled promises

<p>I bought a tablet from pep store at President hyper on the 11th of May and was told that should I encounter problems with it within 7days I must return it for an exchange, I realised that the battery doesn't last even a few hours despite it not being used. On Monday the 16th I took it back but then I was told they will contact MTN and call me with feedback. On Wednesday I got a call to come collect the tablet, I got the shock of my life when I was told that I must keep the tablet as MTN found no mistake with upon requesting a refund that was also denied. The sales person (Moeketsi) who assisted me when I bought the tablet was present on both occasions and the manager (Vicky) wasn't helpful at all instead she was very rude and disrespectful. I want the tablet to be replaced or I must be refunded.</p>
