But they were told at the Robinson Road clinic that they would only get the free trial after signing up for a package, and they left disappointed.
The would-be customers, who did not know each other, then gave Dore Aesthetics a one-star review on Yelp, a social networking website that lets users post reviews and rate businesses.
Then earlier this month, they received letters of demand sent by Parwani Law acting for Dore Aesthetics. The letters demanded they remove their reviews or face legal proceedings.
................. However, some reviewers noticed that the letters they received were not from Parwani Law but instead bore the letterhead of Dore Aesthetics.
These letters had a virtually identical format as those sent by Parwani Law, but they were signed off by the "legal department" of Dore Aesthetics.
Mr Parwani said his firm had nothing to do with these letters.
................. Criminal lawyer James Ow Yong of Kalco Law, who saw the letter, said it was worded "as though it was from a lawyer or law firm".
He noted that it is an offence under the Legal Profession Act for an unauthorised person to act as an advocate or a solicitor.
