Credit account payment not updated

I made a payment of R8500 on the 06/10/2015 at Woolworths store in jhb kerk street processed by Katleho Koali on acc *** provided by customer services. I got an sms a few days back that my account hasn't been paid, I called and spoke to Tracy who told me I needed to send proof of payment which I did yesterday morning and receipt of was confirmed by Ammaarah. She also told me someone will call me this morning at 10 to assist however I still await the call, instead I keep getting smss from Woolworths to make payment, when they are failing to service me and fix/update their systems.
