Poor service from Zinhle ngwenya of VWFS

Very poor service from Zinhle ngwenya on 25 May 2021. She refused to check the 6 month arrangement that I made with Shannon Naidoo on 18 March 2021. My payments are due by 15th of each month. She refused to understand and agree with the customer. I have been paying the arrangement before the 15th and she was torturing my mind that I supposed to do it on 15th. I have kept to my arrangement for two months and paid R12067 on 3 April (which was payment I made towards the 15 April 2021 installment and I paid R12067 on 10 May (which was for the 15 May 2021). She was giving me a hard time understanding the arrangement, cut me off while I spoke and eventually I slammed the phone. She refused to go through the notes that I previously made with Shannon Naidoo on 18 March 2021. I want a manager to call me and acknowledge I kept to my arrangement. VWFS was paid prior to the 15th why are they harassing me with unnecessary calls?

My account no. Is ***
