Non bankmed member gets a claim

I have not been a member of bankmed since 31 Dec 2011, only to find a statement for a claim made by a Dr. Mohmed Shaikh, for patient Suemshan, on the 15th of May 2015. Firstly it seems Bankmed doesn't know what they are doing as claims are processed against customers not bankmed members. I contacted the bankmed ***** line, absolutely pathetic and not assisting at all, defeat the purpose of having a ***** line. Phoned bankmed customer service, spoke to Doreen and not actually assisting as bankmed is making their problem my problem. Please ensure to resolve this matter and ensure that no claims can be made against my details as I will take this matter to the ombudsman, because a ********** claim is made against my name, plus, change your accounting department processes to ensure when customer accounts are closed no claims can be made against their names. Absolutely pathetic!!!!
