Bad service

I have had an account with woolworths for over two years . I have consistenstly paid before the 1st of everymonth. In February I processed a payment using internet banking. Unfortunately I did not include the account number as my referrence number. I got a call from a certain guy on the 12th, I explain to him that I have processed the payment and he gave me an email address to ff my proof of payment. Three days later I was called by a lady, I explained again and forwarded the payment to the same address. A day later I recieved an email asking me to give the account number and my ID so that they can match the proof of payment. A day later I recieved an sms that my account has been submitted to three credit bereaus .I find that totally inconsiderate .Because I made the payment on time and had proof and I emailed on time . I dont even want to start detailing the negetive consequences that it has on my credit profile and my risk profile . It was really uncalled for and very disturbing for such a big reputable company
