I purchased a 55" LG CX OLED TV earlier this year and since I've had it there have been problems with the audio desynchronizing from the video, and also buzzing from the TV speaker at lower sound frequencies. I first contacted LG about it weeks ago, and it took 1 phone call and 3 customer service chats over the span of an entire week just to get a service "agent" to contact me about it. Every time, the person on the phone/chat would tell me I'd get a call within a day or two, but nothing happened at all until the last CS chat when I refused to end the chat until I got a call.Even after I was contacted, the whole process has been incredibly frustrating and I've gained nothing so far. The service agent asked me to provide a video of the problem via email but initially did not provide me with an email address to send it to. I had to wait until the next time she called me to get the email address, because LG would not provide me with any way of contacting my service agent. I sent the video to the provided email address only to be told a couple days later that they do not accept YouTube links (or links at all for that matter) and I would have to send the video file by email, and additionally it would have to be under 20MB... This is impossible as even a 56sec video taken on my old iPhone is over 100MB. LG did not provide me with any alternative to provide a video of the issue.After that, my agent tried to call me a couple times while I was away from my phone to tell me that they are "still working on it" but I still could not return her calls, because calling back on the same number only puts me through to the useless call center. It's been a week since the last time she called and LG have not tried to contact me again, and they are also ignoring my emails. There is no online customer service portal for me to check the progress of my case or upload evidence to either. This entire process is EXTREMELY poor and feels like it's designed to simply frustrate the end user into just giving up. For as large of a company as LG is, this is absurd.LG, you clearly have an overwhelming number of 1-star reviews for a reason. Why is your customer service still this horrible? You need to do better, and for crying out loud fix or replace my damn TV already.UPDATE 6/7/2021: Finally got a call back from the "agent" at LG (Pau). They said they spoke to the "engineer" about the problems with my TV, and the engineer is claiming that the audio desync issue is not a "fault" and is a "normal function of the TV". So according to LG, it's completely normal for a $3000 TV to randomly desynchronise the audio from the video almost once a day, requiring the user to power cycle the TV to correct it each time. I've never heard such an absurd excuse in my life. LG, this is utter rubbish and you know it. If you want to say problems like this are "normal" then you need to put it in the product listing. I'll be taking this up with consumer affairs if you continue to treat me like a fool and refuse to do anything about this.
