Makro *****ulently not paying my refund after I have returned the items bought.

On 2.5.2025 I bought 2 heater at Makro online fur R798 and on their arrival i was not happy with the quality. 11.5 I called spoke to Nwabisa Skade who arranged them to be collected and advised that me to wait for my refund which I never received. I sent numerous emails to makro and I have been pushed from pillar to post to send my vabk statement confirming the payment on one of the emails oli was told the payment was never received ie the R798 then asked how did I receive the order without payment then I was told it would be investigated. Later on in June to July I was told to send proof of payment again abd that was added more than once. Then I was told refund will be done only when I send my bank statement. I ended up loosing my cool because today I still do mot know what proof of payment do they want except my bank statement which they declined to accept. I either need confirmation that this money was paid to me because I have never received or the refund that I was told is due back to me. Email is *** contact *** .This us rather urgent cause I stopped following up on this because I was annoyed but at the end of the day if I paid and returned the goods then I must get back my money.
