SAMSUNG SADNESS

On the 28/10/2020 I ordered an A51 phone dual sim from the Samsung estore. On the 3/11 it arrived - fantastic! Not. Wrong phone. Single Sim arrived. Since then I have phoned 4 times and emailed 7 times. I have been advised that my refund had been processed on the 3/11 - I was also advised that turn around time for the refund would be 3 - 5 days. The phone was collected from me on the 13/11 - it is now the 6/12 and I still don't have my refund. All I get is that it has been processed and the promise of being advised further never happens without me making a phone call or another email. This is ridiculous!!!! I have to pay my credit card for something I don't have because someone in dispatch didn't bother to check the order correctly. I had assumed that the credit would be back into my card before due date of the 8//12, so I wouldn't have to make payment and then have a credit of R7485 in my credit card. COME ON SAMSUNG! You're an international company. This is disgusting.
