Disgusting Service & NO Sense of Urgency to Resolve "finding" Payments

I made an eft payment to my account on the 30/04/2024 and after multiple phone calls and whatsapp chats with different contact center agents and speaking to a Manager, my payment has still not been found and allocated to my account. I've sent in my proof of payment more than twice and was told "the correct reference number and banking details was used so we unsure as to why your payment didn't go to your account". It's been almost 2 months since this payment was made and it's still not been allocated to my account. This is disgraceful to say the least! If it was me missing my payment they would have been harassing me almost all day for payment. I want this sorted out ASAP! I am fuming and disgusted that there is no sense of urgency from HPs finance team to get this sorted out!
