WORST SERVICE EVER

I made a payment towards my visa Card at a Woolies Waterfall Corner on the 13th of August with my debit card and for some reasons my payment was missing and never allocated to my account. I don't know how is it even possible when my account number reflects boldly on the receipt. I have been receiving demand sms and phone calls and on numerous occasions I have advised the person on the other end that I have made the payment already. On Monday the 17th I took it upon myself to investigate by contacting the Head office, instead of them investigating they made me derive back to the store to get a sales transaction journal. Got there and the store doesn't have a fax or email facility to forward this document to their Head Office, boom.... I have to wait for the next day to fax this at my work place. A day later I get an email that they cannot rely on this but they need a copy of my bank statement, which I got and send to them. Again today, the 20th of Aug I get a mail that they need the banking details which shows which account I paid, now really???? Wasn't this paid at a store, where do I now get Wollies banking details when I swiped my card to make this payment. Let me sit back now.
