Poor MBD employee manners

I was called by a coloured lady at 10:13 to remind me of a payment due.

after the message was given she asked me if she can put me on a debit order and i responded she rudely dropped the call in my ear without even saying thank you or anything.

Can i ask that this company rather contact me on email only because the employee that called me does not have any manners, how was this person screened for the position.
