Disappointed

I am very unhappy with the service I am getting. I sent through an claim refund for 23 August 2023 so many times and every time I am told the claim was paid for 26 July 2023. Last time I checked 23 August comes after 26 July 2023. I even called and was told to contact the whatsapp number but no one even responded to my massages. This is very poor service and worse of all I had always gotten great service until this point. I don't know what more I should do just to get my refund. Proof of payment is also attached the date on that is also 23 August not 26 July.
