FND ***** and debt harassment

Someone opened up a ********** account at FNB using my cell phone number, which led FNB to phone me twice a day asking to speak with this person. After explaining to the everyday that i am not the person they are looking for they continued to harass me everyday. Eventually they stopped calling but have now given my number to numerous debt collecting companies that continue to harass me everyday. I am fed up now as this has been happening for 2 years now and all i ask for then to remove my number from their data base and leave me in peace.
