Rude collections agent!

Good day,

I have recently been in contact with you regarding a payment arrangement that was accepted and confirmed via email from Edgars in January 2019. I have been paying a bit more than the payment arrangement this past few months. I received an sms that my account is in arrears, which obviously would happen as I have a payment arrangement in place. I just received a call from ********** 800 from Tulani in the collections dept that literally spoke over me the whole time as I tried to explain I have an arrangement in place already, he kept on telling me thank you for receiving the email??? He clearly didnt listen to a word I was saying as he kept on repeating himself with things I never said. I asked him why his calling when I have a payment arrangement in place already and he asked my paydate? Told me that R890 is due by the 6th of the month? I get it that a collections dept is busy, but how is this man having a one way conversation? How can he not understand a simple question? The calibre of staff you hire is appalling and rather upsetting. If you are going to get anyone to call me, please make sure they have manners and dont have a hearing problem!
