Woolworths Bad financial service

I had a woolworths credit card. I had difficulty with my repayments for a while after I was unemployed for a while. Although I still made a payment each and every month of what I could effore at that moment Woolworths still made a decision to summons me. I then made payment arrangements with their attorney. After a few months I got a phonecall telling me to make my payments directly at woolworths again since I kept my side of the payment arrangement. This is where the trouble started since there was no correspondence from anybody involving woolworths after that. I kept on making payments of R1000 every month to woolworths for about a year then I received a sms fron Consumer friend to tell me no payments were made. I phoned woolworths they told me that they cannot open my account its blocked and they wont be able to see my payments I then phoned consumer friend that told me they cannot see any payments that I have made for the past year Now my problem is WHY IS THE CORRESPONDENCE SO BAD BETWEEN CONSUMER FRIEND AND WOOLWORTHS? WHY CANT WOOLWORTHS SHOW THEM THE PAYMENTS THAT IVE MADE Why havent anyone told me to keep all my receipts as proof? Where has the money gone that Ive paid?
