bad service

My name is Siyanda Umeokoli my number is ********** 485. I am very disappointed about the service I have been receiving at FNB for the past few months. I have made calls and emails requesting for my bank account to be downgraded as the charges are just too much. Till this date I have received no feedback only once did they send me an email saying my account is in minus therefore they can not change my account type. I think you guys are *****'s who do not care about your customers at all. I am moving my money else where and would never advise any one to use your bank as it is a complete *******.
