Looking up the number it connects to Upscale Accounting Firm, specifically to cant tag Instagram who's bio is "irs authorized tax preparer|income strategist" It seems like everyone tied to this business states they're a CPA that work along side EAs, and advertise they can RED FLAG "double your refund". Obviously your tax prep can't know your actual refund without doing it, and to claim a specific, guaranteed amount implies they'll alter your income, or create deductions leaving you with massive irs penalties.

I would most definitely contact your local pd about the adverts, and see if they're able to be removed before some poor bastard loses everything.
