Bad customer service

I am writing to express my dissatisfaction and disappointment with Daly Credit, you guys do not know how to treat customers fairly and your staff is very *********** because nobody for your organisation allocated my payment for the 2nd of June 2025 for 300 rand and most recently I made payment on the 2nd of May 2026 I see that payment hasn't even been allocated and from last year I spoke about this and the agent gave me a email to send my proof of payment to *** but up until now there was still not resolution and then yesterday I get a call from some Mbali and she has given me another email *** to send my proof of payment but up still no resolution and I have been sending messages to your WhatsApp line and sent proof of payment to the WhatsApp line but nothing has happened, you guys really need the skillset to handle customer complaints promptly and efficiently
