Bad service

I went to Makro on 2nd of May 2025 to buy a few things for the house. My payment method was pay just now. I did everything right and payment went through on my side. The lady that was helping me advised that the transaction did not go through on her side hence no slip was generated. She told me that I must refresh my app and that I will get a refund ,we waited for about 10 min and no refund still. She called someone who I believe is her superior who told me that I have an option to leave the goods behind and wait for the refund which according to her only takes a day. Well, that was not going to work for me because I had bought things that my mother needed for her health. So, I was told that I can pay again since the other transaction did not go through (System timed out) and they will have to query the matter for me. I used my last money and paid again, now I am sitting here with no electricity because I am still waiting for my money, I cannot even go back to the store because I do not have petrol. They are not even communicating with me or providing feedback. Now I have to pay my 2nd installment with pay just now but Makro are claiming not to have received the money.

Merchant *** pay just now ***
