poor customer service at Morkels

My mother bought Samsung TV, Sony sound system, 15 Kg LG washing machine, Lounge suite and fridge on November 2014. June 2015 Samsung TV wasn't displaying so we returned to the shop to be sorted. Its three months now still waiting for TV to be repaired and we paying every month for TV which we not using. They don't bother themselves to notify us with the status of the TV instead we're after them to check the TV status. We even had a chat with the manager, but still he could not assist us. Poor customer service from manager arguing with us instant of sorting the TV to be back soon as possible. My mother got a call on Friday 11th 2015 from Morkels staff confirming that the TV is ready and can be collected but then again Morkels staff member called my mother on Saturday morning 12th 2015 telling her that the TV is not ready yet. So for me personally they're playing mind games. I am addressing this issue to you head office so that it can be sort out and willing to take further steps. We no long interest in the TV, we just need to be Refunded all the money have been paid for it, so that we can go elsewhere to buy a new TV. Morkels shop they can keep the TV.
