Paid for but not working...

On the 5th of February , I purchased a Sansui Tv online and it was delivered at home on the 22 of February, upon my return on the 16 of March I unpacked the tv and connected it, then I found that it the screen is damaged on the inside and shows no picture, the damage can only be seen once its switched on.

I contacted Klass again and asked for a reference for my complain so I can escalate it, he p,romised to escalate the matter himself , which he didnt do.
