Poor service, if so it can be called

I bought a 50inch Sinotek tv for R6000 from P&P Worcester on 1 July. Upon setting up the tv, it fell and broke because of a flimzy stand. We returned it to the stor on 2 July, where the store manager confirmed the stand was faulty. Only on 23 August i was informed that the damage was for my own account, and if i wanted the tv fixed, i had to pay an additional r3500, and that for a Secondhand screen. I immediately lodged a complaint again, and finally heard from them again today, September 28, still refusing to replace or fix the tv. It's been almost 3 months now, and it's taking these people ages to respond to queries.
