Very poor customer service

I have been having a query regarding my 6 months loan balance my account was debited on the 26th of September but when I check my mini statement on my app it showed that I didn't pay my September installment.i called the call center and was not happy with the feedback I left it hanging..so today at about 16h16 I get a call regarding the payment I missed so I ask this person it's male by the name of Sbongile who was rude to me didn't want to disclose his surname when I asked..even hung up on me while still talking to him...wanting to know where I should send my prove of payment for them to see I a debit order went through from my account..

I am so disappointed at the service I got I was once a call center agent and I know one should give out their name and surname when calling their customer and very wrong to hang up on a customer 😕 not sure how finchoice works.
