I have received automatic response calls and have answered to run up their phone bills hoping they would stop calling. When I refused to give my card details the 'director' I was passed to became offensive and also told me that by dialling 9 at the start of the call, I was paying for the call, after being informed by the operator that the call was free and was being paid by Calypso Cay, the company in question
Having checked with my telecom supplier, this was a blatant lie, this is the calibre of people working for this company, DO NOT USE THEM!
I am certain they are using the worst type of marketing and should be closed down.
