BAD SERVICE

I have vehicle finance through Absa Bank and fell behind with the installment. i have made contact with Koketso Sekati and Friday, 05/02/2016 i received a very disturbing call from one of the consultant. i told the person that i have already made arrangements with someone else and he was very arrogant and told me that they cannot accept the amount that i will pay at the bank. when i spoke to Koketso i have agreed to make payment on the 06/02/2016 of R1500.00 toward my account . I also told him that i am aware that the amount is little but i am willing to make payment. after the cal on Friday i was so stressed and when i went to the bank at 10am the doors was locked due to the fact that there was a lot of people already standing in line to be helped. i know that the account is behind and i am going to get this up to date at the end of February 2016 but to be threatened and told that people from the bank will come to my house with regards to the care. i am in so much stress that i dont know if i have to cry or scream. i have had financial difficulty and it has been sorted as as i said i will make sure that the account is being paid up to date at the end of the month. please assist
