LG Electronics - The technician not put proper vacuum to my air conditioner

Dear Sir / Madam,

I am writing to you to raise an issue about: Consumable Electronic

The issue that I have experienced was: Before ** days ago I complaint to put vacuum for my air conditioner but they are not properly put vacuum to my air conditioner, because during vacuum process the R** refrigent is removed from outdoor unit before putting vacuum using vacuum pump. But the technician not remove the refrigent from the outdoor unit , he put directly without removing the Oxygen mixed refrigent from outdoor unit this will causes malfunction to air conditioner and dangerous to human because the oxygen mixed refrigent is not removed means it lead to blast so it is dangerous to humans , "IF MY AIR CONDITIONER IS BLASTED YOU ONLY RESPONSIBLE FOR THAT INCIDENT". Take immediate action for my complaint.

It occurred on: */**/****

I request you to remove the oxygen mixed R** refrigent from my air conditioner outdoor unit and put vacuum and refill new R** refrigent. Otherwise I remember that "IF MY AIR CONDITIONER IS BLASTED YOU ONLY RESPONSIBLE FOR THAT INCIDENT"

I look forward to your prompt response on this matter. I would like to keep a complete record of my case, so please reply back via this email account.

Yours faithfully,
