Bad customer service

FNB ***** department is terrible. I got an email saying I received money *****ulently into account. Despite my response and attachments of where I got the money from. Non of the consultant's are available on the phone. Numerous calls were made from the Newcastle branch to Nukeri Beverly, Samantha Malagasy. I have been coming to the Newcastle branch from the 7th of Jan and still my matter is not resolved. This is affecting me negatively because I can't pay school fees, buy uniform and stationary due to my account being Frozen
