R2660 missing and nobody can assist.

I PURCHASED AN ITEM OVER INTERNET AND PAID R2660 VIA EFT. THE MONEY WENT OFF MY ACCOUNT. AFTER A WEEK MY ORDER DID NOT ARRIVE AND THEY AID THEY NEVER RECEIVED IT. I WENT ONLINE TO RESEND PROOF OF PAYMENT, BUT WEREN'T ABLE TO AS APPARENTLY THE TRANSACTION NEVER TOOK PLACE EVEN THOUGH THE MONEY LEFT MY ACCOUNT. I HAVE BEEN TRYING SINCE MONDAY TO GET MY MONEY BACK. EVERYBODY THAT I SPEAK TO SAY THAT IT IS EXTREMELY STRANGE, BUT NOBODY CAN ASSIST. THEY KEEP ON TRANSFERRING ME TO ANOTHER DEPARTMENT WHO WOULD THEN REFER ME BACK TO ONLINE BANKING. I HAVE MADE 6 CALLS TO ABSA. ALL OVER 30 MINUTES LONG. NO RESULT AFTER 4 DAYS. NOBODY CAN EVEN TELL ME WHAT THE PROBLEM IS OR WHO WILL FIX IT. ON MONDAY THE GUY SAID THAT HE IS ESCALATING IT TO IT. ON WEDNESDAY THE LADY SAID NO ESCALATION WAS EVER MADE ON MY ACCOUNT. IN THE MEANTIME I HAVE LOST MY ORDER THAT WAS A SALES ITEM SEEING THAT I COULD NOT PRODUCE PROOF OF PAYMENT EVEN THOUGH I HAVE PAID. SO FRUSTRATING. WHERE IS MY MONEY? HOW DO I GET IT BACK? WHY CANT ANYBODY HELP ME? I AM ABOUT TO CHANGE BOTH MY ACCOUNTS TO FNB AS SOON AS I HAVE RECEIVED MY R2660 BACK.
