Bad Telesales Customer Interaction

I had a rude person calling me from the FNB Enterprise Online Banking Department with the reference number FJL63629. I was to be a sales lead from a call yesterday but her attitude does not warrant her position. Surely you are to KYC (Know your customer) and their needs but clearly, its either she is or was acting dumb. I am not sure what her name is since I was too upset and hung up the phone but usually calls are recorded, so please follow up on the call recordings and take her in for a disciplinary hearing as that is not how you conduct yourself to your potential customers. At the end of the call, I also told her to ask someone else to call me but to now, no-one has contacted me, so I think she must be trying to sweep this under the carpet, but people like her must be exposed for bad service to customers causing a bad reputation to the banking name.
