Unhappy client

I am not happy with tyme bank on the 29th July 2022 I have transferred money to Moja internet vuma account and the money show that it went through and few minutes later I'm charged R3 for failed transaction, but the money is not in my account anymore and did not rich Moja,when I call on Monday the 1st Aug I was told they are having technical problem and was given a reference that will be resolved on the 9th. My question is why does it take so long to refund me while it's their ******* system at fault I'm so mad cause I need that money as we all know economy is bad there's no money that goes uncounted
