Reference number

Yesterday, 11 April 2016 I received a call from woolworths stating my account is in arrears, we did not pay the March payment. So I queried with my wife who notified me that we settled the account on the 17th of March. This morning I phoned Woolworths to discuss this matter and I was told that we used the incorrect reference number, the same reference number that we used for ALL the PREVIOUS EFT's, but this month it is incorrect. I have been on a call with Woolworths for almost 40 minutes to resolve this issue and the last lady I spoke to was supposed to get someone to help me. I held for another 10 minutes before I decided to hang up. THIS IS THE MOST PATHETIC SERVICE I HAVE EVER RECEIVED..almost an hour's airtime lost without the query resolved. 50 minutes of my time wasted that I could have spent on income generating activities, lost..Pathetic service from a major retailer...
