LG Electronics review: Overcharged repair service without refund 1

Our LG dryer started to show the error code D80 which means air flow is restricted, I hired professional duct cleaner but error code was still snowing.

I called LG to set up out of warranty repair! They told me that diagnosis is $125 but I should pay the flat fee of $350 and if I need to repair that’s including everything! But if I decide not to repair and the person comes for only diagnostics, they promised me to refund the money minus $125 (diagnostic fee) . Technician came, checked everything! Only thing he could think of was lint has wax build up so direct us to clean but didn’t need a repair! So I called LG to ask for a refund! She told me that it will be refunded but it takes a month so I waited, but never got refund, so I called them back and they told me that because it was flat rate service, money will not be refunded! I spoke with supervisor, they did investigate our initial conversation with a representative and I . They confirmed that I was told by an agent that they will refund if I don’t repair! Out of warranty department requested billing department for a refund, they rejected! I submitted the claim for president, next day I got the text saying that because I agree to pay flat rate, I will not be refunded! Which I NEVER AGREED ON AND THEY HAVE CONFIRMED RECORDING ! Still haven’t got my money back and I submitted claim again and this time they IGNORED my email completely and they never reached out to me! I can’t believe a big company like this can SCAM people for small amount of money.
