False advertising no customer care

I made a booking on10th January with advertised price on and paid booking in full 13th January an agent called to advise that the advertised price was incorrect and even though there company guarantee booking made by them are 100% its not true . The booking was cancelled and now 24th January I am still waiting fir a refund . When making payment it is immediately debited from my account and transferred to business account yet when the business makes payment it goes via other routes . What must I still do to get my refund . People be careful when making a booking with Safarinow.
