Review POOR customer service !!!

Customer service , non existing!!!!
Staff take your document and go into a room , a office and does not tell you what is happening !
when I go in after 10 min to tell them that I would like to Change the purchase item.
I was told that I can not go in
After a 10 min more . I told them that they do not need to continue with the application

As a customer I was not informed as to that they are doing behind closed doors with my ID and payslips
this is not a good practice , as when my " application" was taken it was done at a table on the sales floor

If the process was made clear as to what is happening, if would have been better.
But just to be told that I can not go in , is completely un expectable
I could under stand if they was busy with banking or some practice that had a security Rick
but this was not the case
And no explanation was given, even after I went out , no one even made the effort to phone me
so clearly your company does not need or want turnover !!and is just willing to lose customers

I will make sure that all my family and friends Know about this incident, and will Not support your company

Thank you
