Discovery International Claims department

I am now going into my 6th week after I submitted a claim to Discovery. They assured me I was covered for travelling abroad. They insist on a breakdown of my fee for £250, although I have sent them 3 e mails from the London Dental Clinic that they do not give breakdowns, they only charged me a standard emergency fee of £250. They answer me with the same word over and over and I am now ashamed even mention to this London Dental Clinic about my Health service. Do not ever, ever believe Discovery that you are covered by Discovery for overseas travel. it is the worst experience of my life dealing with them and I am now close to a breakdown because of their bad service.
