Is CashSend a *****?

IS ABSA *****ING FROM THEIR CLIENTS VIA CASHSEND SYSTEM? On the 26th of October, I tried to withdraw money from ABSA cash send that I received, I put in the Voucher number, pin, and it also requested my name, Surname and ID number and then I got an error 55, unauthorized transaction. I went to the bank ABSA next to ATM, they told me to contact the sender, the sender went to the bank and they said there was a withdrawal on the same date and time was there, but I couldn't withdraw, because I got an error Is ABSA *****ing from their clients by hiding behind claims that their ATM is hacked?
