Bad service and luck of understanding

On the 25th March I received a call around 8:50 in the morning a lady by the name of Shannen called says she is from Wesbank and I should give her my ID number, I then asked her the reason for the call as I can't just give out my ID number, she told me that she cannot disclose any information I then asked her how will I be sure if I am speaking to someone from Wesbank, the lady told me that if I cannot confirm my details I should just call Wesbank, why would call Wesbank when I don't know what's the reason for the call.... She hang up On the 26th March I called Wesbank and spoke to a team leader by the name of Xabiso who I asked if Shannen was from Wesbank, which he confirmed that she is an employee there, I then requested him listen to the call and get back to me as I didn't like the manner and tone of voice that was used by Shannen, before I hang up I asked him what was the reason for the call and he didn't know

Today at 12:09 I was called by Shannen's team leader who told me that she doesn't see anything wrong with being called by a stranger and requesting my Id

According to her I was supposed to give my details just like as I am aware that I have an account with Westbank

With the ***** rate being so high I am highly disappointed with the level of service and luck of understanding from the consultant to the team leader as the only thing I needed is to find out the reason for the call so that is can make it a bit easy for me to trust that I am speaking to someone from Westbank

Anyone can call me and tell me they from Westbank and I should provide my ID and I would be a victim of *****
