Very unhappy and disappointed

I took a loan towards my laptop at Cash Converts Midrand and everymonth without fail I ensured that the loan was paid on time. On 31May 2023 I forwarded a WhatsApp on their WhatsApp service inquiring how much I should pay so that I can collect my laptop. To my surprise I was bluntly told, unfortunately it was pulled on the floor on the 18th of May 2023 after I paid on the 05 May 2023. From that day to date I've been battling to add to my frustration all the people I spoke too seem not to care instead they tell me they cannot retrieve my laptop from the person who bought my laptop. The issue at hand here, is that I do not owe, I've never skipped a payment. My laptop was maybe sold erroneously because one of their employees did not do their reconciliation hence it was sold. Instead of them being apologetic over this issue, they were very unapologetic, rude and bul**** me. They even further told me that my laptop is sold, and they cannot retrieve it from the buyer. They had an undercity of telling me that they can replace it with a better laptop. I don't want another laptop; I insist I want my laptop not any other laptop. Because my laptop is still new, and it was bought abroad hence I cannot exchange it any how. From the 31 May 2023 to date, I send daily WhatsApp's demanding feedback and at times feedback is not forthcoming. From 01-05 June 2023 I was told they are trying to retrieve my laptop from their customer. To my surprise on 05 June 2023, they demanded for my laptop slip (proof of purchase) as if their laptop was bought at their shop while it was not bought at their shop. I gladly provided the slip and their contract and then asked how much I should pay. They advised me to wait as the matter was referred to the owner. On 06-08 June 2023 they blue tick my conversations and ignore me! I've been very patient and been treated very unfairly........At this stage it is not clear where is my laptop, no proper feedback is received and no way forward. WHO SHOULD TAKE A FALL FOR THEIR STUPID MISTATKE, CLEARLY NOT ME. They should not shift their blame but take responsibility. I am demanding my laptop period.
