Harassment of Standard Bank Staff

Received a call from a lady claiming to be from Standard Bank . This person did not want to identify themselves and give a reason for call but wanted me to confirm my details which I refused. I told her its wrong number. She then called again and again did not want to identify herself just saying she is from Standard Bank wanting me to confirm my details. She was asking for a name that was not even mine and continued to harass me calling out the incorrect name. After a brief heated argument due to the incorrect name requested and the rude unprofessional manner in which she addressed me I ended the call. She then left me a voice message saying that due to my voicemail she has confirmed that I am the person she is looking for and blocked my card. My voicemail does not coincide with the name she was looking for and infact implies someone totally different. For this reason I am closing my account with Standard Bank due to the manner in which they deal with their clients.
