THEFT, FAILURE TO REFUND ME MY MONEY

I made an excess payment on my Woolworths card on the 2015/06/25. I sent through my proof of payment along with my banking details 2015/06/26. I was told to follow up by a consultant (Call *** )on Monday 2015/06/29 as I was assured it would be forwarded to Finance that same day and would be action-ed and that the refund would occur by no later than the 2015/07/01(This didn't happen). I followed up 2015/07/29 and found out that nothing had been sent to finance and thus I requested AGAIN!!! for this to happen and somehow the proof of payment was received but not the banking details, HOW DOES THAT HAPPEN WHEN IT'S ALL IN ONE EMAIL?!.If that was the case why was this not re-iterated previously?? I followed up 2015/06/30 and I was told that it had been sent to finance and that the transfer was in progress and re-assured that the refund would INDEED be done by 2015/07/01 as per previously. THIS DIDN'T HAPPEN!!I followed up AGAIN!!2015/07/2(Call Ref#:***)guess what the money still hasn't been transferred!!WHAT A SURPRISE!! I followed up AGAIN(Call Ref#:***) now it will only be transferred no later than 2015/07/06....IS IT ACTUALLY GOING TO HAPPEN...... THIS IS THEFT.
