RCS get cash is nothing but frustration

I app**** for the RCS get cash function on the 2 march 2019 waiting 48 hours for the money to ve deposited into my account. The time passed and no money and no feedback from RCS, after phoning them they said they dont know what happened but will try again, another 48 h passed and still no money or feedback this time they indicated that the account number they used was wrong (so they just left it and didnt inform me) fast forward numerous attemts and tryin to use different accounts and always waiting 48 h and today is the 14th march and still nothing. And everytime i phone them they pass the buck to FNB stating its them thats having the problem. Now my question to RCS is apparently there is no issue with FNB when you deduct money from my account but you cant make the slightest effort to try and assist my on a product you offer. Worst service ever
