Why would the vendor want you to remove your review?
Surely you weren't saying his e-liquid was shit, they are all shit and he is a shit vendor...you were saying that you, personally, didn't like that particular e-liquid? I presume.
Why would they take it so personally?
Found it, read it, had a laugh! and thought it was a fair, honest (and funny) review of your own personal opinion. You even took the blame yourself!
