Smart device issue

My issue can be folloqed via rb Jacobs. <br> I received a Samsung j5300 led tv. From day one the usb port never played any formats except 2. I phone the gurua I was told that it only plays the two. Qhich was nonsense, its a smart TV. I tried sorting it out for how long. Up and down costing me a fortune on calls. I tweeted my problem emailed my sory to rb jqcobs the 3Rd. Nothing was done. I had been sitting with a useless tv paying for it. Now ended by selling it at R4000 loss. As the guy was willing to have it fixed. Its absolutely pathetic. People should watch oit if this happens to them. It seems to get swept under the carpets. I have opened a new acc and want to close fnb one. Service like this nah. Not interested
