Im now paying for the charges On the 4th of jan j. Q ngema deposited 500.on the same account number *** but now om receiving calls saying i never pay than where did the 500 go. I phoned absa one consultant told me to tell the person who sent the money to ask nedbank to email absa to reverse the funds back to his account another consultant said the see no 500 which came in the account yet we have the nedbank statement that the transaction went through i cant withdraw it cos the card is not working and i cant get a statement, i cant go online and check absa is not even helping so wt should i do
