Ewallet

On the 10/06/2021 I sent money to someone using ewallet and twice. I then wanted to reverse one transfere but was unable. I had phoned fnb ewallet services for numerous days and they were not answering. On 15/06/2021 I went to the bank and I phoned from the branch only to be told that the amount has accrued 1cent bank charges and that is why I cannot reverse the funds. I request was made and was told that the funds will only be available after 48hrs and tomorrow is public holiday and it does not count. I am very angry and very disappointed by my bank fnb because this to me does not make any sense. Someone must follow this up ASAP.
