Rightly said and totally agreed! But Brother, that's called learning from experiences and gaining knowledge with the passage of time.
I admit, it was wrong to not recommend ZIC in May 2018, as I did not know much about oils and brands, by that time. However, with the passage of time, I have tried to learn new things and gain knowledge. Learning is a continuous process; May 2018 Vs May 2019 makes a lot of difference! 
(Jo, zyada tarr suna, zyada tarr logoon ney keh dia, maan lia, but now, I try to do a little research before posting).
If one buys ZIC from zicoil.pk or any other reputed website, or authentic store (i.e. oil is 100% genuine & original), then there is no harm in using it.
