Poor customer service by Nedbank Internet service

Poor customer service by Nedbank Internet service and Internet banking call center. On the 7th of June 2022, I sent money to myself because I forgot my card at home and need to do my groceries but Nedbank cardless service was offline and I couldn't get my money instantly. The message i got on the receipt was that my pin for instant money was that it had expired so I gave up and went back. On the 9th of June 2022. I called the call center informing them of this problem and I was told my money will be returned back to my account within 48hrs. I went to the Nedbank at the O.R. Tambo branch and they were offline. I call again on the 13th of June 2022 and I was promised that my money will be returned and that the lady from the call center will call me but till today my money is not turned. I am so disappointed. I coud have saved so much but I am now spending money I don't even have in making calls and driving to branch to be told my R300 will be refunded but till date its not. My cellphone number is ***. My name is Palesa Monokoane and all I need is my R300 back
