telephonic contract agreement

On the 08 of June 2015 @ 17h15 ,I was called by a lady which I forgot to write down as I was driving to take up the loan contract so she s busy verifying my information,she is busy laughing and giggling which I found it unprofessional so as she's proceeding she asking me about the period of how long have I been staying in the address then inform her that I've living there since 1994 so she says yoooo aren't you too old to live your parents I felt unsalted and she so sarcastic and rude when I asked her if the loan has an insurance then she rep**** by saying : Mr Nkewana did you hear me saying anything about the insurances so immediately told her that I'm unable to proceed with her because she was very rude and told that I want her I will talk to her supervisor . So I strongly feel unfairly treated as a client as I deal with client myself . Hope it was the first and last time people are assisted like that, very ********* . Since calls are being ''recorded\ please investigate and take her for customer orientation service."
