Poor customers service

Good morning my name is lydia The lady from the call center called me this morning inconjuction of one month missed car installment.the lady by the name of selina doesnt have a way of talking to clients. She was very arrogant to me and she even threatens me of sending people to come and collect my car if I dont pay the installment. I told her I'm in the hospital im very sick but she continued to harass me over the phone.i said I will pay the amount but she persisted. I suggest call center stuff should be well trained on how to deal with customers.
