I’ve written previously about the Pinergy TV advertising that incorrectly advertised their CallSave 1850 number as a Lo-Call number (which is actually the 1890 number).
Below is a screenshot from the CityJet contact page as of January 2015 where they’re referring to their 0818 number as a Lo-Call number.
As of today having checked their website, CityJet have removed the LoCall description from their 0818 number on the contact page.
Though, it’s now the only contact number on that page where they don’t provide a cost for calling.
