SAMSUNG NEVER AGAIN!!!!

I purchased an expensive TV from Samsung SA Online and did not receive everything in the box as promised on the website advert and spec list. I queried it with the online store team and was told that I’m wrong, despite providing the evidence to the team. I took it up again with live chat support on three separate occasions (whom could not provide me with any resolution despite promising to get back to me the next day and did not) and now the entire team is just ignoring me on all emails! Totally pathetic service from Samsung. I’m now trying to return the TV and buy something from another brand. My new kitchen is due soon and I will no longer be supporting Samsung with purchasing their appliances. I will also now have to go to the Advertising Standards Authority to lay a complaint against Samsung for false advertising. This is just crazy!
